Bur Oak Chronicles is based on facts known about bur oak tree growth. Bur
oaks and oaks in general are monecious, meaning 1 house. They have male and female
flowers on the same tree. Therefore, in this tale, a male or female voice may represent
the tree.
Many Thanks!!
To Dr. Bill Chaney, whose 1993 Tree Physiology course at Purdue University’s
Department of Forestry and Natural Resources, sparked the idea while I was preparing
an assignment on bur oak trees. Yes, I have been working on it since then.
To my Nurnberg American High School classmates who’ve encouraged me to
finish the story and countless other friends and family who’ve supported me in this
endeavor.

Chapter 1 Lost or Found?
I was lost! Jamie McPherson, star reporter, lost!! My first assignment with the
Forester Gazette - down the tube! I could hear the Chief chuckling now: “Check out the
story of the giant trees moving from place to place. Then you can report it as an urban
or in this case rural myth!!” He chortled loudly! I think he was testing me to see if I’d
actually go out and now, I’m lost!
I kicked the brown dust at my feet and thrashed my hat around at the powdery
particles floating towards my face! Hack! Hack! This is what happens when a city
reporter moves to the middle of Kansas. How am I going to finish my bur oak report?
Where are my landmarks, buildings, concrete, or billboards? How can I find my way
with vast expanses of nothing! Not even a simple sign post! Humph! What kind of
place is this? Why did I accept this assignment? How am I supposed to find Bur Oak,
Kansas? AUGH!!
I slumped against the dusty door of my trusty, yellow jeep. The sun stood over
my head like an exclamation point. Salty sweat rolled into my eyes and I was hot and
hungry. What better thing to do now than eat lunch and reread my editor’s directions?
I yanked the crumpled map off the front seat and remembered the last sign I saw said
“Bur Oak – 52 miles.” That was about 80 miles ago! I was sure the ranger man in the
green truck I met at the sign said I was on the right path. Could he have been wrong?
I grabbed my thermal lunch sack, removed my turkey on marbled rye, clutched my
cold canteen of water, folded my legs beneath me and collapsed to the ground in the
little shade my jeep could provide. Munching furiously, I focused on a small, grayish
dust spiral to the east and noticed the puffy clouds beginning to dot the sky like a
painting taking shape. You seldom see that in Chicago.. Yawning, I watched a large-
winged, brown bird squeak as it floated above my head. I wondered if it might be an
eagle as I watched it circle lazily, catch an updraft and hover for a heartbeat. Looking
for lunch I presumed. Closing my eyes between bites, thinking of my predicament, I
slouched ever closer to the ground.
5
Suddenly I was coughing madly. Dust and sand filled my eyes, nose, and
mouth. Blech!! A brown fog covered me. Where did this come from?

Chapter 2
Branching Out with Cork
I jumped up to get a better look and a tree branch smacked me across my
upper arm. I turned toward the offender. “Hey! Watch what you’re do…?” I was
staring into the face of a real, live tree!! “AUGH!!” I screamed. “AUGH!” the tree
screamed back as it ran off.
Oh, my granny! I must be losing my mind, too much heat, not enough water.
No, I’m not crazy. I saw it. There was an eye, two eyes squished into the bark, and a
slit for a mouth that was moving and screaming! The eyes looked at me with
astonishment or fear; I couldn’t tell. It happened so fast! The branches or arms or
whatever they were, waved and flailed all over in its haste to get away from me. I
looked down at the mark on my arm to prove it to myself. This is nuts! I stumbled
back against my jeep, scrambled to the hood, and realizing I was holding my breath,
filled my lungs with grimy air and coughed violently. Standing on the hood, I looked
for evidence of the tree and there it was, lumbering down the little hill with rumbling
and scratching sounds toward a grove of trees. And dirt, everywhere a trail of dirt
followed the tree.
The sound and dust died away as the tree moved further from me. Then, I
heard more; it started low like your stomach rumbling just before dinner. I peered in
the direction of the sound and spied more brown puffy clouds coming from the west
side of the prairie. Hastily, I jumped in my jeep and headed for what my eyes couldn’t
believe. As I drove I saw movement and more dust clouds along all points of the
compass. What was happening?
I drove toward a spot where all the trees converged, ventured as close as I
dared, and parked. Quietly, I exited my jeep and walked slowly like a gymnast on a
balance beam into a grove of trees that were walking with me! And they were talking!
I heard voices from every direction.
“You said we’re here, but where is here?” A disgruntled small tree said to a
larger one. Another said, “I wanted to stay home and be with my friends!” The tree
7
alongside it said, “And I told her, if you let those squirrels bring leaves into your tree,
they’ll stay all winter!”
The strangest assemblage I had ever seen was unrolling before my eyes. I
twisted and turned so fast that I made myself dizzy and sick. Trees gathered together
like they were having small meetings. I inched toward the closest group. I was either
invisible to them or they didn’t care that I was there. No one – er tree paid any
attention to me.
Two large trees were having an animated discussion with a willowy sapling
hanging nearby. Its branches waved all around as if it was giving directions. I thought
of my Uncle Louie and chuckled. You had to be ever watchful when he talked.
Hands and arms flew like they were swatting mosquitoes on a hot summer evening.
“Once the clans arrive,” I overheard “Uncle Louie” say, “join whichever group
is telling the story you want to hear. Nobody wants to miss a word and the elders are
so committed to passing on information, they are willing to repeat what they know to
all interested listeners. But hurry, you might miss the beginning! Get to the closest
group!”
The other tree nodded, grabbed the twig of the small one, and headed in the
direction of a circle forming around a massive tree. I followed in wonder. Trees telling
stories! A row of thin, spindly, tannish-colored trees, maybe two-three inches in
diameter, sat below a towering, multi-branched tree. It was huge! I bet my eight
cousins would have trouble circling his trunk with their arms spread wide. When this
tree begins to talk, I suspect it could put Grandma Helen out of the talking business!
She loves telling stories of her grandparents. I listened eagerly while inching my way
through the stems and leaves of all the trees around me.
Cork, as I heard him called, began, "Bur oak twigs are stout, yellowish brown,
and become pubescent after their second year.” “UH, UH, UH,” a small tree on the
front row jumped up and down with excitement. “What’s pub-scent?” Chuckles
floated through the crowd like ripples on a pond.
“OK, who wants to explain to this curious youngster?” Cork bellowed!
8
One of the trees next to the questioner replied cautiously, “I think that’s hairy,
isn’t it? Or at least that’s what my
cousin tells me.”
“Absolutely,” said Cork, “so we
know our twigs are big, yellow-brown,
and pub-es-cent or hairy. Does
everyone see that?” A rush of cool air
wafted through the crowd as all the
trees shook their tops while examining
their twigs and their neighbors. I
noticed Cork emphasized the correct pronunciation without making the young one
feel bad about mispronouncing the word. Very kind, I thought. Pub-es-cent, wow,
what a word. Glad I’m not in a spelling bee! Ahem!” Cork began, “Let’s continue.
We have much to learn and so little time. When the second year begins, our smooth
twigs develop corky ridges.” Cork pointed to the definitely corky ridges along its
lower branches. OOOHs and AAAHs filled the air. The youngest saplings turned to
inspect themselves and each other.
Cork continued,
"Another detail to make
note of is our buds. At the
ends of our twigs, they are
clustered. Who knows what
that means?”
Up jumped a whip,
anxious to share its
knowledge. “It means there’s more than one bud at the tips of our branches.” A
larger bur next to the whip beamed so much I could hear the bark crack!
Cork was pleased as well. He patted the young whip on her leafy canopy.
“Yes, said Cork, “and those buds are called “terminal” because they are at the end of
the branch. Now, find those buds and tell me what you see around them?”
9
Examinations began in earnest. Saplings checked themselves and each other
and shrugs of dismay came from every
corner. I tried peering over limbs to get a
look at the buds myself. I tapped on my
neighbor’s “shoulder”, requesting a peek. As
I scrutinized the buds sitting in a cluster at
the end of the branch, “terminal buds”, is that
what Cork called them? I noticed little hairs
sticking out from around the buds. I poked
my neighbor and showed him what I found.
Suddenly, I realized that they could not only
see me, but they responded to me for the
little sapling looked at the buds I pointed
out, smiled at me, and wriggled his way to
the front of the group.
“I found them, I found them!!” he said with glee.
“Well, well, I believe we have a winner!” laughed Cork. “Tell everyone what
you’ve discovered.”
“Little hairs are all around my buds,” was the proud
statement.
“Great discovery, little one,” said Cork with a wink in
my direction. “Little hairs around our buds are a unique
characteristic of us as bur oaks. Few trees have that trait. We
should be proud!” Cork lifted his canopy and was filled with
pride as were all those around me. My little neighbor danced with glee, giving high
twigs to everyone as he strode back to stand next to me.
“I have another question for one of you in the front row,” Cork beckoned to
the spindly ones. “Now, that we know more about our terminal buds. What about the
buds along the sides of our branches? What are they called?”
10
A quick twig was raised. “Momma and Poppa say they are laterals!” the sapling
responded with much assurance.
“How correct you are, and brave to go out on a limb answering with such
speed,” chortled Cork. “These lateral buds along the sides of your branch are smaller
than the terminal buds. But, wherever they’re located, you can be very sure they’re
mostly obtuse and tawny pubescent like the terminals," Cork stated with a look of pride.
Behind me I heard a shrill, "What's obtuse and tawny?" Muffled chuckles filtered
through the crowd. An older bur bent down and whispered to a tiny tree, "We'll look
those words up when we get home."
"But, I want to know NOW!" pleaded the little one. "Etch your question onto
this parchment and I'll explain as soon as Cork is finished." Furious scraping sounds
along a small, thin piece of bark followed as the young sapling worked with the
intensity of an ancient scribe to permanently display her question for later answers.
“Young whips are rightfully curious,” I overheard an elder bur on my right
whisper over my head to a tree on my left.
I turned to look at the “whip”
they were speaking of and quickly made
note that this tree was much smaller than
the saplings in the front row, about an
inch in diameter I guessed. So the
smallest are whips and the next in size
are saplings. Good information! I’m
sure my editor will love this.
“Speaking of branching,” Cork
bellowed to focus their attention on the
primary purpose of the gathering. “Let’s
compare ours to the human amongst
us.”
I whipped around to face the
front. Cork was moving my way! When
11
his roots were settled next to me, two of his massive branches lifted both my arms to
shoulder height. “All of you burs lift your branches like the human has done,” Cork
instructed.
The sound of branches moving in unison was reminiscent of the night I
watched the midnight train roll past the rural crossing near my parents’ home in
upstate New York. Calm, quiet and then a deafening roar!
“Aha!! Something’s different. What is it?” questioned Cork.
Everyone looked at themselves, each other, and then at me. Aside from the
fact that they were trees and I was a human, the differences escaped me.
Suddenly a young sapling blurted, “They’re arranged differently!! The human’s
arms are straight across from each other and our branches aren’t!”
A collective sing-songy OOOOH was heard throughout the gathering.
“How right you are! Our branches are alternate," Cork replied. "That means
they are not on the same plane. The human has opposite arms. Most tree species have
alternate branching, but some trees, such as our cousins, the maple and the ash, are like
this human with opposite branching.” I felt at once so very different from the burs, but
at one with the opposite-branched trees. I resolved to find some when I got home. I
scribbled more notes.
"Back to buds!!" Cork loudly proclaimed.
"The branches stem from buds." Cork began to
chuckle with delight at his own jokes. "Seriously,"
Cork tried again but the shaking of his leaves
made it difficult to believe proceeding was on his
mind. "There are other types of buds with
different purposes," Cork began again. "Flower
buds contain the beginnings of flowers. Then
there are mixed buds comprising flowers and
leaves."
12
"It must be very crowded in there," I overheard a young whip say to another
while inspecting his branches. "No wonder they explode in spring."
"Boom!" said his neighbor while several young saplings chuckled nearby.
Cork's bark creaked with an obvious frown while he was peering in the
direction of my neighbors. I guess only large oaks get to make jokes.
"BUDS and BRANCHES!" Cork shouted. "Branches that form from terminal
and lateral buds are strongly attached to the tree for they start growing from the
beginning of the development of the branch. They are connected to the larger branch
or trunk deep into the heart of the wood. One of Cork’s gnarly branches quickly
reached out to a limb on a tree nearest him and gave a mighty tug! The surprised
owner lurched forward! “STRONGLY attached!!” he said, repeatedly pulling on the
branch. “Because that's where our
terminal and lateral branches start
growing; deep inside, beginning
when we are less than one year
old.”
“Yikes!!” squealed the bur
whose branch was the object of
our discussion. He slithered
backwards, holding it close to his
trunk, fearing Cork’s reach and
more pulling.
“Now,” Cork continued,
“there’s still another type of bud
called adventitious or dormant
that forms just under the bark
anywhere on the tree. If a branch
forms from one of those buds and I pull on it, CRACK! It’s easily pulled off because
it is not strongly attached! It doesn’t form deep inside. DEEP INSIDE!” He
bellowed and pointed to his insides.
13
“Branches formed from these adventitious buds are accidental,” continued
Cork. “They form on our newest wood, the wood right under the bark which is
usually due to wounding. After the wounding, the tree begins to make callus tissue to
close over the wound and the dormant buds right under the bark take this as an
opportunity to begin making branches. Since this attachment doesn’t start deep inside,
the branch is weakly attached."
"How does this wounding occur?" I whispered to my neighbor. Sound carries
well, I discovered, or Cork had microphones planted in the group for Cork
immediately responded, "Who asked that?" A flurry of branches pointed my way.
"Thanks!" I muttered, eyeing all near me.
"Well, now those pointing at our human can provide some answers," said
Cork.
I tried to conceal my gratification, but the smirk on my face was obvious.
"Storms?" The sapling next to me offered reluctantly. Cork's face cracked
again, but this time with a wide grin. "How right you are! Storms cause branches to
snap off and bark to be torn away. Then the tree begins to repair itself."
I believe the sapling's shoots grew a foot at that moment, with obvious pride in
his answer. Older trees winked and branches nudged bark to bark as their pleasure
showed in the young one’s response.
“Are there other ways that wounding occurs?” Cork continued to query.
Several groups began to whisper amongst themselves. Some branches pointed
my way. I was feeling a bit uneasy. I soon learned why.
“HUMANS!!” wailed an old bur in the background moving my way.
“Humans!” he continued as his strides quickened.
I was looking around in search of an escape route, when two middle aged burs
stepped between the charging bur and me. “Stormy”, I now call the sapling at my side,
joined them to protect me.
“It’s not this human’s fault.” I heard one bur gently whisper to the older,
enraged one. The old bur paused, looked at the others, straightened up, and strode
away from me. One of the intervening burs placed a twig on my shoulder and nodded
14
its canopy slightly. Stormy grew closer and wrapped a tiny twig around my leg. I
looked down and mouthed, “Thank you.”
Wounding? The enraged bur seemed to connect me to it. What did my
protectors mean, “It’s not THIS human’s fault?” Quickly my mind ran back to last
week when a group of kids skipped down my street stripping little branches from
young trees. I never thought of this as a big issue. Perhaps, I have much to learn, as I
brought out my paper and pencil to make notes of
this increasingly complex system of trees.
"LEAVES?" questioned Cork. "From
where do they develop?”
I sensed Cork’s desire to turn our attention
away from the interruption, and I was brought
back to the present, but I wanted to know more
about what provoked that bur’s response. Maybe
later I would discover the answer, though I had
some doubts that I wanted to hear the truth.
“Leaves!!” Cork stated again. “Where do
they begin?”
Intense activity began. Heavily leaved
branches were lifted and inspected. Sherlock Holmes himself couldn't have waged a
better investigation. But, I heard no response. It seems no one knew the origin of
their leaves.
Cork’s crown shook from side to side. "I am amazed. You hold your lovely,
leafy canopies so proudly, but don't know how they begin. Look closely at the base of
a leaf. My dear friend, Lobelia, will dig deeper into your leaves, but for now we'll do a
little examination. At the base of every leaf where it attaches to the stem is an axillary
bud. Next year's twigs and leaves open from there."
Astounded OOOHs swirled through the air.
Cork's bark creaked and groaned. "All this terminal, lateral, axillary, dormant, and
adventitious bud talk leaves me weary. That's a lot for an old bur. I need to rest now."
15
Burs continued to investigate themselves and their neighbors’ leaves. I had to
laugh, for their inspections reminded me of my cub reporter days at the Toronto Zoo
watching baboons pick insects off each other. I chuckled with reminiscence as I
worked my way to the rear of Cork's group and out into the grounds. While
wandering, I frantically scrawled my thoughts of the morning's activities on my
cellulose paper with a wooden pencil. Then, I became aware of an uneasiness with
which some burs eyed me. The watchful glances and nods of a few apparently friendly
patrons acquired at Cork’s group seemed to dispel the crowd’s fears. I decided,
however, to switch to my fine-point Bic pen and write-in-the-rain paper, which
consists of more cotton fiber than wood fibers. I hoped it would ease their fears and
signal my desire to be accepted. It appeared to work, for many trees gently tapped my
shoulders or tousled my hair as they passed me. I felt like a member of a football team
who’d made a good catch.
As I watched them move away, I overheard the young whip in Cork’s group
who wanted to know about pubescent, tawny and obtuse say with impatience, “Now can
you tell me!!” His father, patiently said, “Hold up your twig. Take a look at your buds.
Do you see those very tiny short hairs?
Remember what Cork said. That’s pubescence.
Now, obtuse is a shape. It’s rounded with no
point.” The young one nodded vigorously,
beginning to see tree characteristics in a
different way. “But what about tawny,” he
squealed?
Tawny,” pondered the elder tree, “is a golden yellowish-brown color,
something like the hide of a deer. Beautiful isn’t it?”
The little whip beamed while looking closely at his golden buds. “I am
beautiful, aren’t I?” “Yes, and that’s why we’re here. There are many reasons to feel
proud of ourselves,” beamed his father.
16
Chapter 3 - Ashley’s Growing Pains
“I am older than you!!” “No, you’re not!!” I spun around to hear a heated
debate and scuffling between two young whips. Larger trees shuffled over to
intervene.
"There’s no reason to argue like this; it's easy to see who's the oldest," said an
approaching bur.
Gasps could be heard from the by-standers. "She’s going to cut them down
and read their rings!" The crowd shuddered and yelled. “Ashley Oak, don’t do it!” A
huge guffaw bellowed from this moderately large bur. "That’s not what I’m going to
do." Ashley’s large branch motioned
for the two arguers to move closer.
Gingerly they obeyed.
“Hold out your branches,”
instructed Ashley Oak. “Now look at
your bud scale scars." They looked at
their shaking branches with wide eyes
and then at Ashley with considerable
suspicion.
“What is the matter?” said
Ashley grinning, “Can’t you find
them?”
“Find what?” replied the two
young ones still shuddering with fear.
Actually, I noticed they were not alone in wonderment. Many older trees were
searching their branches for bud scale scars, too. I began to grin. Then a neighboring
tree gave me a slight nudge with his branch and said, “What’s so funny? Let’s see your
bud scale scars.” I immediately cancelled my smirk.
Ashley overheard and let out a deafening laugh. “Humans don’t have bud scale
scars. They don’t even have terminal buds.” This little joke apparently touched
17
everyone’s funny twig, for waves of giggles infected the entire crowd. It was several
minutes before calm returned to the group.
Finally Ashley continued, “Branch growth occurs yearly from terminal buds
located at the ends of every branch. A covering of bud scales protects the bud and in
spring the bud opens, the scales fall off, and the branch grows. POOF! Like magic! It
happens year after year. Everyone,” Ashley boomed, “look at your neighbor’s
branches and share a branch with our visitor.”
Suddenly, twigs appeared all around me. Many tiny peals of laughter could be
heard as adjacent bur’s twigs appeared under my arms, through my hair, and even in
my ears.
"Attention, attention!!" Ashley grinned with delight.
"Find a bud, then notice a circle going around your stem.
That’s the bud scale scar! You young ones can tell your age by how many times
the bud scale scars appear on your twigs.”
“How about counting them?” Ashley inquired, “Anyone?”
I could hear plenty of numbers adding up. “I’m four, I’m five, and I’m seven!!
Wow, this is fun!! See, I am older than you!!!”
"What's all this space between bud scale scars?" questioned a medium sized bur
in front of me. “Is there a name for everything?” I could see the region in question. It
reminded me of the area between my elbow and wrist. I raised my arm for an
inspection and a young sapling beside me placed a twig next to my arm. We looked
down at our appendages. Then his bark creaked with a shy grin. The similarity was
striking. I wiggled my fingers in response and my sapling friend wiggled a few leaves.
I grinned and winked at another new found friend. "The spaces between buds are
called internodes, and yes, there is a name for everything." Ashley stated with exactness.
"Do you have a “code” in your node?" laughed a jokester on the front row.
Ashley turned with mild displeasure, yet chuckling. "I believe that belongs to
our human." I reached for my nose and bark splitting laughter began everywhere. It
was so infectious I joined in.
18
"Remember, the place on your twig," Ashley continued, after regaining her
composure, "where leaves are attached is called a node, and the area on the twig that’s
between the leaves or nodes is called the internode."
"AAAACCHOO! AAAAACCHOO! We all have colds in our nodes!!"
The young ones were at it again. If burs could roll on the ground from
laughter, they would have looked like bowling pins shaking after a strike. I had to
admit they were having fun learning.
"Young burs!" Ashley's booming voice straightened everyone up. "We have
much to learn in our short time together. Remember, you carry the story of how you
are made back to your neighbor burs back home."
I noticed one of the whips involved in the original “I’m Older than You”
debate looking puzzled.
Her bark scrunched
together top to bottom
and side to side. “But,
Ashley wait,” she said.
“If big trees grow bigger
around every year, what
happens to the branch
growth? How come the
old ones can’t tell how
old they are from their
branches?”
“Superb
observation!” Ashley
boomed with delight as
branches waved madly.
“What happens to your
leaves every year?”
Ashley inquired of the curious one.
19
“They fall off!” the whip proclaimed proudly.
“Correct, and so do some branches.” Ashley continued. “So counting bud scale
scars in older burs might not be accurate!! It's the aged ones who can only tell their age
from their rings.” UUUUUWWWs were heard from every corner of the group!!
I was puzzled by this response and looked at my neighbor who made the
proverbial slash across the throat but at its middle. “EEEWWWWWW!” I responded.
I wondered what these rings were about. Maybe I’d learn more at a later stage.
“Back to branch drop, which occurs in most tree species, another way trees are
the same and yet at the same time very different. A stunning mystery! Sorry, I have
fallen from our original story. Where was I? Oh yes, my friend Lobelia will cover
leaves in detail, but for now I’ll just say that small branches drop from larger limbs in
the same way leaves fall. The process is called abscission. You’ll understand this perfect
puzzle after hearing Lobelia.” Ashley was silent as if the stories were complete.
Whispers and murmurs erupted in little pockets throughout the crowd. I
looked at my new sapling friend, I’ll call him Internode. “Are we through?” I
questioned. Internode shrugged his branches, twisted his facial trunk, and rolled his
eyes around with wonderment as well.
Finally, a mid-size bur spoke up. “Excuse me, Ashley, there seems to be
something missing.”
“Oh, is there?” Ashley pondered. “What could that be?”
“Twig growth makes us taller, but how do we grow in girth?" the bur
questioned.
I chuckled to myself. My Uncle Jeff would have known the answer to that
one. Let's see: pizza, ice cream, and cheese -- all the right stuff made HIM grow in
girth!
“Rings!” Ashley blared while shaking a giant branch into the air with great
drama. “Rings!” was repeated as she focused toward the sky. The entire crowd waited
and looked skyward. The expectancy was as thrilling as waiting for Santa to descend
the chimney. Any moment, I knew something would happen. Usually I munch a
cookie at such a time, but nothing was left of my lunch.
20
So there’s more about rings? My interest was piqued.
Earlywood and latewood these ARE the answers!” Ashley stated with much
theater. I looked around for Sir
Lawrence himself. Surely this
was a Shakespearean audition.
Ashley shuffled to the far end of
the “stage” as I was now viewing
events and turned slightly
forward as if begging for a
soliloquy. “Yearly growth occurs
in two parts. Inside our trunk are
two types of vessels like tubes
moving water and nutrients from
our roots to our leaves. Another
vessel moves sugars from our
leaves to our roots. Large vessels
are produced early in the growing season, hence the name earlywood. Later in the
season, latewood vessels are produced. These are considerably smaller.” Spinning
quickly around to face the front, Ashley blurted. “WHY do you think these large
vessels occur in the earlywood? HMMMM??” The crowd was silent and everyone’s eyes
shifted from side to side, looking for an answer which reminded me of searching for
my brother Craig while we were playing hide and seek.
Ashley straightened and propped her lowest branches on the middle of her
trunk. “Think, think, think,” she gently prodded. “What happens in the spring growing
season?”
“OOH, OOH, OOH! I know!!” Internode was jumping with joy.“Yes?
Young one, what do you think?” asked Ashley.
“In the spring, I'm growing fast and I need to take up lots of water and
nutrients from my roots. So I have large vessels to do that,” the young one replied.
21
The applause was thunderous. My sapling friend turned as red as a sugar maple on a
Connecticut hillside. Ashley beamed as well.
Internode paused and looked thoughtful. “What about the latewood, what is it
for?” “My, my, I think you should be in my advanced class, such inquiring questions!
Does anyone have
an answer?”
Without
thinking I blurted
out, “In the fall
there’s less moisture
and growth so the
vessels are smaller
because they won’t
be sucking up
much.” “Incredible!” laughed Ashley. “My job is complete! Even the human is
learning! Good Night, all!”
I said, “Wait, Ashley! What do the rings have to do with annual growth?”
Ashley turned to the group. “Can anyone answer the human’s question?” “Do
we add a ring of earlywood and latewood each year?” squeaked Internode with trepidation.
The crowd erupted with waving twigs, branches and cheers.
Ashley beamed and bowed in agreement. As she marched off with a great
flourish and to tremendous applause. This time everyone was satisfied.
So that is the significance of the rings and annual growth. I was intrigued with
everything, but the connection between leaf and branch abscission was a curious one. Is
that the word -- abscission? I must have been muttering aloud, for Internode answered
me.
“Yes, abscission is what happens to leaves. Are you going to hear Lobelia next?”
“Yes, I believe I will. There is so much to learn and so little time.” Visions of
the White Rabbit scurrying around Wonderland flashed through my head. Where is
my watch?

Chapter 4 - Lobelia's Leaf Tales
After recovering from Ashley’s twig tale, I spied a gathering of equally eager
listeners under an ancient bur oak whose giant limbs spread 200 feet across the
landscape. I was in awe of its size and grandeur. The sheer beauty and strength of the
branches drew me below its crown. Many young burs had found their way to the front
and as I forged ahead I heard one in the crowd asking questions of the giant tree.
“Lobelia, why do my leaves turn a golden yellow in the fall, but the leaves of
other trees turn bright red?” a mid-sized bur standing proudly on the front row
questioned.
An enormous grin cracked across Lobelia’s bark. "Our leaves are very
complex and
composed of many
cells. Inside each of
the cells are hundreds
of tiny organelles called
chloroplasts, which
contain chlorophyll
pigment, she said with
her lilting voice.
Organelles, is
that for playing
marching music?” chuckled a marching sapling behind us. Lobelia didn’t look very
pleased with the interruption, but realized more explaining was necessary.
“Every living thing, even our human, has cells throughout our systems and
inside these cells are pieces or organelles that when put together like a large puzzle
keep us alive. One of the organelles in our cells is a chloroplast. Can everyone say
that?”
“Chlor-o-plast”, we all responded.
23
“Correct, and that organelle is green most of the time. During the summer,
this green color or pigment is responsible for photosynthesis. Without this we could
not remove carbon dioxide from the air, mix it with water from our roots and in
sunlight, turn all that into carbohydrates.” Ashley chimed in with a flourish. “Each of
our leaves is a tiny factory pumping carbohydrates to every cell. Quite simply, if the
factory quit working, we would die," she stated with a wavering voice.
Gasps of shock created a shudder that rolled through the crowd like the
beginning of a gentle spring thunderstorm. A young one regained her composure
and inquired, "But that still doesn't tell us how our leaves turn a beautiful, golden-
yellow color in the fall."
With eyes gleaming in delightful mischief, Lobelia responded, "Ah, the
yellow is always there."
"No, it's not," said an impish youngster.
Lobelia continued, undaunted, "Yes, it is, but it's masked or hidden by the
green chlorophyll. During the summer our leaves are green, but when the short days
and cool nights of autumn begin, the yellow or carotene pigment that’s hiding in the
chloroplasts begins to shine through. The green chlorophyll disappears and our golden
yellow colors are displayed beautifully throughout the forest."
A couple of young saplings began swaggering around giving "high leaves"
to each other. “Burs are cool! Burs are cool!" they chanted. Lobelia interrupted
their gaiety, "Other tree species show beautiful, colorful pageantry in the fall, too.
Behind the chlorophyll in other trees are pigments of red, orange, and purple.”
All around me, canopies shook in agreement that other trees also have
beauty.
“What happens after our leaves change color?” shouted a bur.
“That is a spectacular mystery!” Lobelia mused with pleasure.
“Autumn brings days with less light and cooler temperatures and changes
beyond color begin to occur within our leaves. Look at a leaf. Do you see where
your leaf attaches to your branch?” A giant whooshing sound accompanied their
positive response as canopies waved front to back.
24
Lobelia continued, “Another cell job begins. A layer of cells form at the
base of the leaf where it attaches to the stem and it’s called the abcission layer.”
“Bless you!!” shouted a few burs. Then Lobelia gave a creaky grin, “I
didn’t sneeze; the cell layer is called ab-ciss-ion. These cells start cutting off water
and nutrient flow to the leaf which causes it to wither, die and begin to make its
way to the ground. This happens with some small branches, as well. I’m sure
Ashley mentioned that process to you.”
“It’s been cut off!” a tiny whip yelled while clutching its bark in an
imitation of strangling. Suddenly gasping, thrashing whips were flailing themselves
across the forest floor.
Lobelia half-turned toward the self-amused display and squinted with mild
displeasure and a half-grin. “Drama school is down the hill!”
We all chuckled.
A voice from the rear squealed, "Lobelia, a bur’s yellow color makes our
leaves special. Is there anything else about our leaves that make us unique?"
Lobelia exploded with delight, lumbered toward the tiny voice and picked her
up with a light squeeze. "MY, MY YES!! I was hoping someone would be inquisitive
enough to ask more questions. Come with me!” Lobelia carried the beaming,
miniscule sapling to the front row, set her down, and sighed. “There's so much.
Where shall I begin? AH, Yes! Everyone, pick up your branch and look at your
leaves. What do you see? You in the back, tell me something about your leaf."
A tall, thin tree directly behind me shouted,
"My leaf, actually all of them, is attached to my twig by a smaller twig."
"That twig holding the leaf to the twig," remarked Lobelia," is called a
petiole
.
The petiole allows our leaves to move freely in the wind, creating cool winds below the
25
canopy." "Cool!" snapped a whip to its neighbor. "Whoosh, whoosh through the air!"
The two young ones wandered through the crowd imitating trees fluttering in a hefty
wind - coincidentally pausing right over my head and fanning me to the amusement of
everyone.
"AHEM, AHEM," Lobelia quietly nudged them and my neighbors back to
reality.
“Returning to the question of what makes us different. Our leaf size, shape, margin,
and
lobes
make us a truly unique species," continued Lobelia with obvious pride.
"I don't understand
margins
and
lobes
," whispered a sapling to the strong tall
bur standing nearby who shook its canopy negatively. Frankly, I didn't either. I knew
margins were at the edges of
my paper, and my ears have
lobes. But, I didn't think that
was what Lobelia meant.
Lobelia overheard the
question and continued the tale.
"Margin is the edge of the leaf.
It's like tracing a river’s course.
You follow along the waterway
moving high into the
mountains and then deep down
into the valleys. Those are our
lobes. Hold up a leaf and
follow the edge. You'll see at
least seven lobes and some of
you have eleven. It's OK to be
a little different. You're still a
bur!"
Lobelia’s voice chimed as the burs raised their leaves, inspecting each lobe.
The variation in lobes was clear to me. Those with the most lobes proudly showed
26
them to their neighbors. However, ones with fewer lobes focused on their glorious
green colors. I mused at witnessing their competitive spirit, so like having the best car
or house. Inside we are all quite similar.
The young "whisperer" near me gently raised a twig. "Lobelia, what else is
special about our leaves?”
Lobelia looked skyward as if in great thought. “Why, they're
obovate
in shape
and generally their size is six to twelve inches long and three to six inches wide.”
Several in the crowd laughed and pranced around saying, "I'm obovate, I'm
obovate.”
What a story this is going to be! My editor is going to love this, I thought, as I
furiously took notes.
Lobelia sauntered over to the joyous group and with a snicker stated, “Exxx-
plain
obovate
!”
As quickly as the “prancers” started their dance, they halted and whispered
with bowed canopies, “UHHH!! Not sure.”
“Anyone else care to try?” Lobelia quizzed the crowd. Silence was as loud as
the seventeen year locust. “You ARE here to learn, remember. How about a pear??”
“A pair of what?” quipped
a youngster.
Lobelia laughed loudly, “I
meant a pear that is eaten.”
“Lobelia, are you trying to feed the
human?” wisecracked another
youngster and snickers filled the
air.
“How ABOUT a pear?”
Lobelia repeated bringing the
group back to the subject. “Have you seen its shape? Slim at the top and large at the
bottom. If you turn a pear upside down, it’s large at the top and small at the bottom.
27
Look at your leaves. What do you see?” I watched the sapling in front of me.
Her leaves were being inspected and twisted up, down, all around. The young sapling
paced and scratched furiously on her bark and canopy obviously deep in thought.
Detective at work, I thought,
taking in clues and figuring it
out.
A crescendo of
awakened enlightenment
coursed through the crowd.
“I see it!” many shouted
as lights of knowledge flickered
like lightning bugs on a warm,
June night.
“What else do you see about your leaves?” queried Lobelia. “Look at my leaf!
It’s, it’s dark green and shiny on top,” came a voice from the young sapling to my
right! “And pale and fuzzy underneath,” shouted another! “Wow, and the base of my
leaf is rounded on the sides and pointed at the bottom!”
“Technically that’s called
cuneate
,” said Lobelia, who was now sparkling at the
new-found knowledge of the crowd. “THIS IS
FABULOUS!!” Lobelia pealed with glee!! "Let's go
back to photosynthesis. We've looked at our beautiful
colors and shapes, but the glory of our leaves holds
wonders beyond belief."
They were like putty in Lobelia's twigs, being
molded and shaped with pride. The air was heavy with
anxious anticipation.
"Remember, our leaves trap sunlight in the chloroplast and remove carbon
dioxide from the air. A wondrous process occurs within our leaves to combine water
and carbon dioxide and produce carbohydrates and oxygen. Carbohydrates are essential to
our survival, and the oxygen produced is indispensable to humans.” Lobelia stopped
28
speaking and a calm quiet flooded the group. The mutual need between humans and
trees was apparent. Respect for each other leapt upward like a spooked kangaroo. I
looked around and inhaled deeply and exhaled as much as I could. It was a moment
of pride for everyone.
“One other thing before we disperse:” Lobelia stated, “the importance of our
leaves to the earth and soil around our roots. I’m sure you’ve heard about our vessels
taking up nutrients from the soil, hmm?” Canopies shook in agreement.
“When I say our leaves fall to the ground and decompose after abscission, I
mean that the leaves die, then fall apart or break down and the nutrients in the leaves
are returned to the soil. At some point, these nutrients attach themselves to water and
up they go again, flowing UP, UP, our
xylem
vessel to nourish us again.”
“WOW! I didn’t
know that! Leaves are really
important,” I blurted out
loudly. Lobelia gently nodded
with pleasure. “Yes, it’s like a
puzzle. Even the smallest bits
are an essential part of the
whole picture. With that I think I’ll send you on to discover more of the puzzle.”
Thunderous cheers and hearty slaps on the nearest neighbors’ trunks ended Lobelia's
tale. I was tossed and twisted as my back and head became the target of many slaps.
The crowd moved in many directions and I overheard my two new sapling
friends, Stormy and Internode, whispering, "Joseph is talking about how you can tell a
juvenile tree from a mature one."
Internode replied, "Yea, I want to find out if I'm there yet. Ma keeps telling
me I'm not sexually mature!"
I was equally mystified. “Trees sexually mature??” I said out loud. The
two youngsters turned and waved for me to follow. How curious? I trailed
quickly behind my new friends.
29
Chapter 5 - Juvenility to Maturity or
All You Ever Wanted to Know About Phase Change in Burs
It was easy to find Joseph, a tremendously old and big tree, surrounded by
young saplings. If they were to root in place, not a ray of sun would hit the forest
floor for the density of their crowns made light penetration impossible. I noted that
interest in maturity is not strictly a human curiosity. It made me think of junior high
study hall when one of my friends found a particularly interesting book in the library
and we all gathered around to glean every morsel of information about becoming
mature.
Peals of laughter and squeals broke my momentary reminiscence. The saplings
were growing restless and louder in their anticipation. I grinned, noticing Internode
and Stormy on the front row. “I can’t wait to hear Joseph,” he wiggled with delight.
In the next instant, Joseph’s voice boomed with such force that the leaves of the trees
rustled and a hush fell upon the group. The silence was eerie. I had once reported
from Charleston, South Carolina, when Hurricane Hugo hit, but this calm, quiet was
unlike any other.
Joseph began, "Who knows what it means to be mature?"
Sapling stems waved in the air with frantic anticipation, but now their rush of
leaves was akin to a gentle whisper. No words had yet been uttered, for Joseph
commanded immense respect. Elders’ eyes rolled as they peered around the area to
see who had raised their branches.
Finally, Joseph eyed Internode and bade him to speak.
He began with a stammer, "I-I will be big and strong?"
Groans proceeded from the crowd. I cringed for the poor little guy.
"NO!” bellowed Joseph.
Now Stormy decided to attempt an answer, "My roots will be secure and I
won't bend in the wind?"
Joseph frowned solemnly at this answer. Branches slowly bent toward the earth
as the others suspected they didn’t have the answers either.
30
"I think your parents have not informed you of the basics," growled Joseph.
He scrutinized the older members of the species. Thick-leaved branches bent with
shame. Muffled coughs were heard amongst the crowd.
"It has little to do with being big and strong, though that may happen when
you are mature. But it is not a SIGN OF MATURITY," Joseph stated with intense
deliberateness.
"Let me begin," Joseph stated with a calm, quiet demeanor. Tensions that had
been slowly mounting were now released as a giant sigh engulfed our surroundings.
But all were lulled into Joseph's mistaken calm.
For next came a boom, louder than the cannons in the 1812 overture. Surprise
mixed with fear radiated from those closest to the front. I was glad I hadn't taken my
place up there. I would have missed the looks on their bark. It was almost comical,
since I knew my parents had never told me about maturity changes in humans either.
I chuckled, thinking of my parents in a crowd of adults being chastised by Joseph. It
was a funny thought.
I was again pulled back from my daydreams to hear Joseph's mesmerizing
voice. "There are several external signs of maturity common to all tree species," he
emphasized, "not just to bur oaks. One is so obvious and I suppose so commonplace
that it is overlooked. A second sign is a trait used by humans in scientific research.”
Gasps of terror were heard throughout the crowd. “Scientific research”
whispered from one end of the group to the other. Joseph calmed their fears. "It does
not involve the cutting of an entire tree, but using a portion of a young stem for
rooting purposes." Relief was immediately noticeable throughout the older trees;
however, the young saplings were not so assured. A few continued to tremble and grab
their parents’ trunks. Giggles began again, but were abruptly halted when Joseph leered
in the direction of the offenders.
"The first sign has to do with spring. What occurs in the spring and is
accompanied by a pleasant fragrance?" he queried the assemblage. One enterprising,
but I fear cocky sapling replied, "Girls!!"
31
Snickers resounded throughout. Joseph looked slightly askance at the young
one, but continued, "Not exactly! But you are on the right track." The sapling
stiffened with surprise and pleasure.
"It does have to do with male and female parts of the tree."
"Oh boy! This is what I have been waiting to hear!" replied the sapling next to
me, excitedly grabbing me around the
neck. Thankfully he wasn't very
strong and he quickly returned to his
position of silent anticipation as
Joseph continued.
"Male flowers appear as catkins
and female flowers sit all alone or in
groups of two or three on the current
year’s small branches or branchlets.
“Hold it, hold it,” said the
cocky, young bur. Did you say that
the male and female flowers are on
each tree? So I’ve got girl cooties on
me? “
“I’m afraid so! But think of it
this way: you don’t need to travel far
to find a date!!” Joseph laughed with delight. “Seriously,” began Joseph, this is called
mon-ecious
’ or one–house, meaning that our male and female parts are located on
one tree. Other trees are called ‘
di-ecious
’ or two houses. That means it is either a
male or female tree. Isn’t that amazing!! “
I was lost in this new world and blurted out, “How do the male and female
seeds get from one part to another?” Joseph was obviously proud of my involvement
and stated, “Blowing wind and bouncing squirrels spread the pollen throughout our
canopy AND the bees and butterflies flitting from flower to flower scattering our
pollen from tree to tree. Without this process, seed formation would not occur.”
32
“Wow!” I said and all laughed, even Joseph.
“Good to see you’re in the spirit of the day,” chuckled Joseph. “Now on with
our seeds which are…,” paused Joseph. Enthusiastic branches shook the air.
“Everyone in unison…” Joseph began, “Seeds are known as “ACORNS!” the
crowd enthusiastically replied. Leaves
and stems shook as many acknowledged
they indeed knew THAT bit of
information. Several OOOHs and
rustling leaves could be heard from the
younger set. There was almost a sign of
relief among the oldsters, that finally
Joseph had mentioned something familiar
to their offspring.
The cocky youngster was not
finished questioning. “How old will I be
when I can make acorns?”
“Brilliant, Brilliant! I can tell you’ll take my place when I move on to Bur in the
Ground. Look around, does anyone have acorns forming?” Joseph replied with glee.
“Well, who has an acorn?” he queried. A few of the whips and saplings checked
themselves out with disappointment on their faces. Some of the medium-sized burs
picked up their branches and shook them in front of the young ones with delight.
They had acorns and wanted to show off.
“AHEM!” Joseph stated with a displeasing frown on his bark. “It wasn’t that
many years ago that you sat where the young ones are now.”
The mid-size burs bowed their canopies low. “We were just showing them our
acorns.” One said trying to squeeze his way out of trouble.
“OK, nice try! ” said Joseph, How old are you three?”
“Thirty-five, forty-two, thirty-seven!” shouted the mid-size burs.
33
“That’s right,” Joseph retorted, “burs must be at least thirty to thirty-five years
old before they produce acorns. It’s just a fact of bur life. There’s a time for
everything and age is one of the marks of maturity.”
Groans could be heard from the little ones. “I don’t want to wait. I want to
be mature now.”
Joseph laughed, “Everyone wants to grow up fast.”
I had to chuckle, too. Boy, sounded just like me! I wanted to drive a car so
bad when I was twelve. I hated waiting for someone to take me places. I was in such
a hurry to grow up!! And then I got there and other things happened as well. Bills,
bills, bills! I must have been muttering out loud for Joseph questioned, “Excuse me?
What about bills?”
I shook my head and came back to the present. “Sorry, just day dreaming.”
“Well, we will move on now to the second sign of maturity as I mentioned
earlier," whispered Joseph, as the entire group bent forward straining to hear its every
word, "but it is - not - as - in-ter-est-ing." The last few words proceeded with such
slowness that I nearly fell on my face with the rest of the listeners as we leaned
forward eager for every syllable.
"UH!!" came the surprised voices from the saplings.
"It is terribly important to the continuation of our species, however." he nearly
growled in retort to the disappointed looks he received.
"Easy rooting," he quipped majestically.
I admit I was as puzzled as the rest. Shrugging of branches and shaking of
leaves, stirred up clay particles on the forest floor. Several took to coughing and
sputtering as Joseph calmly explained.
"Though this is rare, when wood is in the juvenile or immature stage, a broken
branch can be placed in the ground and roots will form." Groans of pain went up as
young and old grabbed their branches while visualizing Joseph's explanation.
"You know how rough the saplings and seedlings are to each other; loss of
branches is inevitable. So while they are young, new trees could sprout from these
losses. As we reach maturity, the ability of these branches to easily root is lost. That's
34
why we must be careful as we age." Joseph spied a few elders that he had seen playing
rough with the squirrels. They peered off into the sky, pointing at soaring vultures,
pretending to have heard nothing.
"You really have nothing to fear,” laughed Joseph, “for it is humans who’ve
taken this juvenile quality and used it to develop new burs or other tree hybrids. I
expect there are many other uses for this trait. It will take some in-depth explanations
that I fear must wait for another time." Joseph began to yawn and stretch his
enormous branches.
Several saplings grew uneasy
fearing that Joseph was finished. They
looked wide-eyed at each other. "Are
there any other signs of maturity?" one
sapling asked another.
An eager sapling raised his wispy
branch.
"Yes?" inquired Joseph.
"What is the third sign, and is
that all?" said the sapling with
trepidation.
"Oh, yes, the third sign," Joseph
pondered. "Withering!" he said with
deliberateness.
"Huh?" was said in comical unison. It was like they were going to begin a song
and someone had hummed the key of C. In fact, I chuckled a little too loudly and all
eyes, including Joseph’s turned my way. I coughed with embarrassment, as I
murmured “I'm sorry” several times. I was really interested in this trait, and I surely
didn't want to lose their confidence in me at this point. "Withered or dried leaves that
remain through the winter. Have you noticed that?” queried Joseph.
Trees on both sides of me shook in unison. “Yes, but why?”
35
“It’s a mystery of our species,” stated Joseph. "But other trees, white oak and
beech, for instance, also exhibit this juvenile characteristic. As the whole tree matures,
the lower immature branches hold onto their brown withered leaves all winter.
Remember, I said these three traits are common to our species, but there are
other signs of maturity unique to other tree species.” "Like what,” squeaked a seedling
behind me? "Oh, thorns, for one," Joseph stated
calmly. "OOH! Like who?" asked one standing
near Joseph.
"Well, not an owl. That's for sure,"
Joseph chuckled, peering in the direction of the
questioner. Laughter filled the arena.
"Black locusts," Joseph stated, “have
thorns as a juvenile characteristic. In fact the
black locust has both juvenile and mature phases
on the same tree. The lower part of the tree may
remain juvenile, bearing thorns and lacking the
capacity to flower, after the upper part has
attained maturity."
Joseph began to tick off other signs of phase change in rapid succession while
I frantically wrote. I didn’t want to miss a morsel of information.
"Leaves of sassafras are different shapes. Immature leaves are lobed and look
like mittens with only a thumb, while others may have a thumb and one finger,"
Joseph continued.
One enterprising and inquisitive youngster queried quickly, "What's a thumb?"
Joseph laughed with glee. “That is a human feature. Next time you see one,
inspect it.” All eyes suddenly turned my way. I could see Joseph chuckling with
delight. In fact his huge, thick branches moved up and down in a wavy motion as
laughter continued in enjoyment of my predicament.
So, I politely held up my hands, not quite knowing what else to do. Threads of
"OOOH!" worked their way through the throng as I wiggled my thumbs.
36
Joseph composed himself but worked to hold back his laughter and delight at
seeing the look on my face. In the midst of the laughter, a yawn spread across his
thick bark. "Enough for now," he said. His giant branches raised skyward stretching
and yawning. "More
stories tomorrow."
As the group
dispersed, I overheard one
elder say to her offspring,
"We can find out more
about rooting traits from
Rooty. Tomorrow! Now
to bed. Dream about birds,
bees, and flowers tonight."
I, too, needed rest. The inquisitive little sapling who asked about thorns
shuffled in our direction. Stormy and Internode motioned for “Thorny” to follow
along. They took my hands and pulled me with them.
Stormy invited me to sleep at his camp. Upon arriving, various ages and sizes
of burs gathered around, recounting their day’s events. The name “Rooty” was
repeated often. I anticipated hearing more intriguing tales tomorrow.
I leaned against a bur to continue listening to their stories with Stormy,
Internode and Thorny curled up beside me and must have been very tired, for the next
thing I knew, my nose was tickling. “Just a few more minutes’ sleep, Maxx,” I begged.
I flicked what I thought was the whisking of my golden retriever’s tail across
my face and opened one eye slightly to see three tiny trees smiling at me!
I rose up with a jolt having forgotten where I fell asleep. Internode, Stormy
and Thorny were waving their leaves across my face and chuckling.
“Come on!!” chimed the three. “It’s time. Tales are beginning.”
They ran off to my left, waving for me to follow, but I spied something in
another direction, and motioned for them to go on without me. Rooty beckoned.
37
Chapter 6 - Getting to the Root of the Matter
Running across the green, I discovered why this gathering of burs caught my
eye. Their size drew me in. While the other groups consisted of seedlings, saplings and
older trees, these were different, and my reporter's mind wondered why. As I made
my way toward the crowd, I felt uneasy. I was sure I was being watched. I searched in
several directions, but saw no one eyeing me like when I first arrived. For the most
part, the bur clan had accepted my presence. I think replacing my wooden pencil with
a ballpoint pen put them at ease. So, I couldn’t understand my present wariness.
I shrugged it off as my eyes were drawn to the assembly surrounding an
immense bur. The size of the tree was remarkable. I had been told that as burs age,
the corky wings upon their branches increase in size and number. By the look of those
branches, I would speculate this one was among the most aged.
The entire group, as I surmised from afar, consisted of larger and older trees. I
approached with respect for I realized I was in the presence of the learned. In many
human cultures, age and wisdom walk together and this appeared true here as well.
This truth transcended the obvious physical differences between the burs and humans.
I found a spot near the rear of the assemblage, and prepared to be fed much
wisdom. Again, that feeling crawled up the back of my neck. Who was watching me?
And why? I looked around. Everyone’s eyes were forward with intense anticipation
of the stories to follow. I ignored my paranoia and hastened to listen. Cheers and
applause were rising. “Rooty! Rooty!”
The voice from within the tree was deeply resonant. “Fellow burs, it is with
sadness that we gather to discuss our roots,” he began. “I look around and see the
faces of my dear, old friends. I have known many of you from the time we were
barely out of the acorn. Tell me, where are the little ones? Do they not have need to
hear this message?”
One large tree from the back boomed, “It is not a flashy subject, like our
shapely leaves, their golden fall color, or our deeply furrowed bark.”
38
“Here, here!!” came echoes from across the crowd. An evangelistic surge was
beginning.
“They don’t understand the significance of our roots,” another barked.
I had to admit I was mystified myself. What was so important about the
roots? The age and fervor of the group led me to believe I had much to discover.
Murmuring began in small groups and soon the din was deafening. However,
quiet overcame the crowd as the speaker’s branches shook. It appeared to be a signal I
would have missed had it not been for the response of the group. “We must
persevere,” the old one quietly began. “We are gathered in this place to remind
ourselves of our common roots, but we must not forget to tell the story of our
underground roots. Unseen is sadly forgotten.”
There it was again, that feeling at the nape of my neck. I knew I was being
watched, but from where? Everyone’s eyes were riveted on Rooty. Who could it be?
My thoughts wandered back to the growing enthusiasm of those around me, when I
felt a tug at my pants leg. I looked down with surprise to see a very tiny sapling
holding on to me. I could see a speck of brown out of the corner of my left eye. I
was being watched. I reached down with my hand to touch the tiny, spindly
appendage wound around my pants leg. It was Stormy!
Ever sat on your dad’s foot, twisted your arms and legs around his calf, and
held on for a ride around the living room? Picture a small tree entwined in the same
manner around my leg. I gingerly lifted my left leg and the tiny tree lifted with me. I
raised my foot a little higher and faster and giggling began. Just for fun I decided to
run in circles. I wasn’t sure who would give first. Motion sickness is my nemesis. To
my surprise, the tiny tree tumbled off my foot and rolled to the edge of a small group
of variously sized trees trudging past us. I laughed as my new friend rolled around at
the base of those trees, flinging and bouncing as if this were a giant, outdoor pin-ball
game. Those gathered around were laughing, too. It took me a moment to realize the
laughter was directed at something else entirely.
My little friend was bound tightly by, appropriately enough, his roots. My
stomach began to ache from laughter as I watched him twist and turn, trying to
39
discriminate branches from roots. I became uncomfortably aware that the laughter
was mine alone as a huge shadow stole my sunlight. It was Rooty, growing weary of
our untimely display.
"HMMMPH!! Excuse me!!" he boomed. "May I be of assistance so I CAN
CONTINUE WITH MY DISCUSSION OF OUR
ROOTS!!”
I was terrified. In my fear, I tried to hide behind my little friend. Again we
made quite a comical sight and twitters of laughter began anew. Papa Root spun so
quickly in the direction of the new offending laughter, the trees standing near me fell
over like bowling pins. With this newest interruption, Rooty stormed to the front of
the crowd and with serene whispers stated, "The matter of our underground roots is
so fundamental to who we are, I can only suggest that those not interested -- LEAVE!
Those remaining will be mystified!" With that comment, all in attendance came to
attention. No one departed. Stormy and I decided it was time to pay attention. Rooty
didn't say a word. We waited. We twisted. We wiggled.
"Please, tell us about our roots," a few voices began. "We want to know."
40
Now, spurred on by the
imploring crowd, Rooty drew up
proudly and proceeded as if
nothing had happened to delay
his discourse.
"Roots have specialized
functions," he stated with a
pause. Then motioning, he said.
"Look at yourselves. Those
heavy exposed roots extending
from the trunk," he pointed
down, "have a very special
purpose. They keep us standing
upright and balanced. As we
grow taller, they grow broader
and stronger. If it weren't for them, we'd topple.”
I suddenly felt my arm thrust into the air. Rooty spied my odd arm waving
madly. With scrunching brow I swear I could hear the bark crack around its large dark
eyes.
"Yes? Is there something I can help you with, Thin Arm?" Everyone
snickered at the apt description of my upheld appendage. I gulped, realizing my
impertinence. I was silent. "Go on," he said with encouragement. Others nearby
nudged me as if to push words from my mouth.
"I’ve seen trees in my neighborhood staked with wires to hold them up.
Doesn’t that work?" I asked. Gasps were followed by guffaws from all corners of the
crowd. Rooty held up his branches to quiet the crowd. "Now, now, let's not
discourage questions from the thin arm."
"I can see why from your experience as a human you would wonder about this
common practice. Staking and guying a tree, however, prevents the natural process of
strengthening our wood and growing our roots."
41
"Let me think, think, think. How to explain this? Hmmm! It's just like your
form of exercise. Our roots’ job is to anchor us to the ground. As the wind blows,
the movement causes the wood in our trunks to strengthen. This in turn helps to
make the roots stronger and longer. Movement sends a message to our roots so if our
trunks don't move because it is prevented by staking and guying, our roots don’t grow
and they become weaker and weaker.” I must have looked strange for Papa Root
asked if I understood.
“I’m not sure I really understand.” I admitted.
“Well, let me see.” thought Rooty. “If you never moved your muscles or
added extra weight to make your muscles work harder, you'd become weaker, right. So,
moving in the wind doesn't hurt us anymore than exercise hurts you. Our roots work
with our trunk to grow stronger and to anchor us more firmly in the soil."
With each word, Rooty inched in my direction, towering and bending over me.
We were now squarely face to face. "Is it clear?" I shook my head up and down
vigorously and glanced around sheepishly. I could see many middle-aged tree
branches folded across their trunks and looking at me rather smugly, as if I should
have known.
Rooty ambled toward the front and cleared his throat to call attention to the
topic at hand and thankfully no longer on me. "Ahem,” he coughed, “we shall
continue. Roots have many functions. Our surface roots anchor us as I mentioned
previously," he said with a sideward glance in my direction. "Then there are our feeder
roots, whose importance cannot be overlooked."
A few younger saplings were beginning to filter into the crowd. One scooted
in laughing and giving a "branch-bow" to its neighbor asking, "Is it feeding time?"
Rooty overheard the chuckles. And turned ever so slowly toward the young ones and
merely said, "Yes, it is, but do you know where and what these roots feed upon?"
Several “Uhs” and “Wells” came from the young ones who just entered, but said
nothing else. Rooty turned to the entire assembly that was enjoying the discomfort of
the youngsters. “What about the rest of you? Can someone tell me about the feeder
roots?"
42
Quizzically, confused faces turned toward each other. One brave branch
fanned the air in response.
“W-water and nutrients," she responded nervously.
"CORRECT!!" boomed Rooty. "But there is one problem here. We don't
actually feed. That's what humans do. We soak up what we need from the soil.
Feeder or soaker roots are tiny and numerous. Here's another question," Rooty said
with great delight. "Why is that important?"
I thought and thought. Rooty's question reminded me of my dog, Maxx, at
bath time. Especially when he's finished bathing and I reap the rewards of his
numerous hairs shaking water everywhere. "More roots, more water," I said out loud.
Even Rooty laughed at that one. "More water is absolutely right," he
continued to chuckle. “The fine roots work their way through tiny cracks in the soil to
search for more water and nutrients. It's an important role for these roots.” “Is that
all there is to our roots? “ Stormy squeaked in my direction.
Rooty began to laugh and throw his branches up in the air, upon hearing the
question. His laughter turned to tears streaming down his bark. “I never thought I’d
hear a young one ask such an important question. Rooty began a chimed response,
Root hairs! Mycorrhizae! ROOT HAIRS! MYCORRHIZAE!! ROOT HAIRS!
43
MYCORRHIZAE!” I thought it was a commercial for Root Grow! His
evangelistic spirit grew with each phrase.
“Listen!! What you can’t see is vital! Do you believe?”
The crowd was beginning to feel its fervor!
“Yes, yes!! We believe.”
“Root hairs,” he said, swaying and talking, “live such a short time.”
Rooty seized on their attention. “Water, nutrients - the stuff of life. We
couldn’t live without them. Do you understand their importance? Thousands of
miniscule root hairs attached to our tiny feeder roots absorb our life blood and then
DIE.” Rooty said with considerable emphasis. “Some live only a few hours. They
perform their vital function and then become part of the soil. It’s a hero’s end.”
Rooty bowed and the entire crowd fell silent.
A quiet question rose from the crowd, “How many of them are there?”
“There
could be
thousands, even
millions
throughout our
root system,”
Rooty
expounded with
passion.
"EEEEEEK!!"
A couple of young whips rushed toward the sudden shrill sounds of their
neighbor.
I froze in fear at the horrifying sound, and then leapt forward as my reporter's
heart took over. A story! Shrieks and gasps flew through the group and I saw young
44
whips flying through the air. Then I heard barking! Barking, I couldn’t believe my
ears. "EEEEK!! WHAT is it??" shrieked the young bur looking at the ground.
A little brown and white beagle with its nose close to the ground stopped near
a large, aged bur and began to furiously dig. I arrived on the scene to discover a black,
globular shaped mass in the paws of the beagle. "What is it?" I questioned as the
young ones scattered and hid behind larger burs.
"AHHH, mycorrhizae!" confirmed Rooty emphatically, “and a truffle.”
"Mi - core?" I inquired. My pen was scribbling madly. "Could you please
spell that? Is it dangerous? Should we evacuate? Do you have a plan?"
Rooty roared with laughter.
I paused to gain my composure. "OK, what is Mi-core-rrz?" I shrugged with
perplexity showing all over me. “And that black glob in the ground, a truffle you say,
what does it have to do with anything?”
"It's perfectly normal," Rooty declared with certainty. "Remember, I said there
are two items important to our root system, root hairs and this, fungi and mycorrhizae.”
He pronounced it as if it was a dignitary entering the Oval Office.
"So?" I questioned with bewilderment.”
"SO!!" Rooty proclaims with
an astonishing pause. "What we have
here is a failure to understand! My
dear friend these globs, as you call
them, are truffles, the fruiting bodies
of our special partner, mycorrhizae.
These fungi, as they are also called, are
evidence of a great work occurring
below the ground. The fungi produce
a fine mat of hyphae or tissue that covers the surface of our roots and mycorrhizae are
entwined with all of it.
“Hold it, hold it!!” I interrupted. “I thought fungus or mushrooms, as I knew
them, were on top of the ground.” Rooty explained, “The truffle is also a fungus, the
45
special fruiting body for oak mycorrhizae, but it doesn’t appear above ground, it’s an
endomycorrhizae, which means it is on the outside of the mycorrhizae but still
underground. And would you believe it. People hunt truffles and eat them. That’s
why the beagle is here. He’s looking for fungus gold!"
A few burs shouted about then, “I wish this truffle hunter would go away.
He’s not digging anymore, but looking at our bark funny and lifting his leg.” I
chuckled, thinking of Maxx!
Then I heard a few squirrels chattering and running through the canopies with
the beagle close behind barking, chasing and being lead out of the forest.
Canopies fluttered in oak applause!
“Thank goodness it’s gone, I have questions,” squealed Stormy. "Why are
these mycorr i-zee important?” Rooty beamed proudly at the little one. "You are
becoming very inquisitive. I like that. Think about it, young one! What do the hyphae
of the mycorrhizae look like?” Rooty probed.
Stormy’s canopy bent forward like Rodin’s “The Thinker”; some serious
pondering was occurring. Suddenly he bounded upward!
“They’re like tiny roots. Lots and lots of them!! More roots mean more
soaking ability. Our root system has increased.”
“Superb!!” Rooty proudly rose up to his full height and beamed at Stormy. In
fact, that reminds me -- our root system! How big do you think it is?” he asked
quizzing the crowd now.
Stormy let out a deep sigh, relieved to be off the hot seat.
By now, Rooty had piqued the interest of the entire assembly. Without waiting
for a response from the group, Rooty marched forward.
“Depending, and I mean depending on the soil conditions, whether it is dry,
wet or in between, our roots spread horizontally two-three times our height.” Rooty
straightened up proudly.
“Wow!!” exclaimed the audience, including myself. I was impressed. I
thought, however, about trees in the city with all the digging for houses, roads, and
sidewalks. I shuddered, picturing what was happening to their roots. Oh, and I
46
remembered the day I planted hostas at the base of my front yard tree. I hacked away
at the roots, making way for plantings. I hope they can’t read my mind. I cringed at
the memory. I was brought back to the present by a quizzical youngster.
“Are we fast?” my little friend bravely asked Rooty. Older trees nearby
grinned and tousled his tiny little leaf canopy.
“Juvenile roots are fast! Like everything else, young ones can’t wait,” Rooty
chuckled. “Actually it's an important strategy. The seedling pops to the surface and
the roots take off like rabbits running from the fox. The seedlings have a head start.
In fact, a taproot forms before the first leaves unfold.”
About that time a cloud of dust flew into our midst. “Did I hear someone say
juveniles are fast?” exclaimed Internode as we coughed and laughed at his entrance.
Behind me came little tapping and giggling sounds on the bark of a tiny bur.
“What is going on?” Rooty bellowed to the astonished Stormy.
“Uh, helping our friends with their roots. You know, tap, tap, tap…..to help them
grow.” His answer was slowly becoming a whisper.
A few smirks were heard from the aged burs.
“That’s not the “taproot” I meant.” Rooty hid a slight chuckle himself. “A
taproot is a single root that grows straight into the ground when the seedling starts to
grow. It helps it stand straight while all the smaller roots begin to inch out into the
soil.” I swear the bark of the saplings changed color as they stopped their tapping.
Rooty continued, “After one growing season, a seedling may have a taproot of over
four feet and a mass of fine lateral or horizontal roots spread out over thirty inches.
“WHEW!!” whistled the large oak near me. “I hardly remember those days.”
I looked down to find my sapling friends bursting with pride. They were
willing themselves to grow through stretching and parading, something akin to novice
body-builders.
“This ability is useful to us burs, because of where we live,” Rooty continued.
“Finding and absorbing water in prairies and other dry habitat is tough. We need
ample roots, root growth, and root hairs, otherwise it will be difficult for us to
compete with other species.” At that moment Stormy and Internode punched at each
47
other and the air, like mock prize fighters, but all they did was stir up more dust
particles.
“So the deep-root myth is true?” I questioned through my coughing.
Rooty turned, strode my way and, placing one branch gently on my shoulder,
stated firmly, “No, it’s not universally true. It is, as you say, a myth. Our taproot
disappears after a few seasons because it was there to help us in our early years. For
most mature forest trees of a variety of species, the feeder roots are in the top eighteen
inches of the soil and spread out way beyond the shadow under our canopy. This
deep-root myth leads to serious problems, especially for trees living in cities. It is very
sad. You may have an opportunity to witness the results first-hand while you are
here.”
I sensed my question fell on a heavy heart and I was sorry I mentioned it.
Then I wondered what was meant by “first-hand”?
Rooty returned to the front and addressed the waiting audience. “Our roots
are vital to our existence! We must spread the message! Radiate from here! Broadcast
what you have learned! We must not give up!”
Rooty ended amidst a thunderous applause of waving branches and leaves,
mounting cheers, and a standing ovation. However, I’m not quite sure how one could
tell; I thought they were already standing. I stood and loudly applauded, feeling a bit
inferior with only two appendages to wave and clap while showing my deep
appreciation for Rooty’s wonderful saga.
The crowd enthusiastically dispersed in all directions, searching for more
stories. Internode ran off in one direction and Stormy was off in another. The older
burs tapped their bark, showing approval of participating with Rooty. I held back a
bit, surveying the possibilities. I, too, wanted more. A small red bird twittered
melodically as it flew effortlessly above my head. Glancing in its direction, I noticed
the beauty of the azure blue sky. There was music in the air. Literally, there was music
in the air and I followed it.

Chapter 7 Chloe’s Ups and Downs
Hmmmm!!! HMMMMMMMM!
Hmmmm!!! HMMMMMMMM!
Hmmmm!!! HMMMMMMMM!
Harmony! Musical harmony! Like a barbershop quartet! I skipped toward the
sounds. Several burs were holding court with many more gathering around. It was
delightful to see and feel the harmony expressing itself in the responses of those
around me. We all swayed to the pleasing sounds. “Xy-y-lem, phlo-o-em,” the chorus
ebbed and flowed. Trees bent and moved to the music. I shifted back and forth to
the sounds as if intoning a mantra. It was infectious, but I had NO idea what they
were singing about.
The humming and swaying slowed. I spotted that same red bird flitting from
tree to tree, twittering and alighting momentarily with the gentle shaking of a branch. I
felt so peaceful; I sat on the ground at the base of my neighbor tree and wondered
with pleasure what I was going to learn. A graceful, mid-aged bur separated from the
harmonious group at the front. I whispered to the bur next to me, “Who is this?”
“Chloe!” was the quiet
reply, “of the Inner Parts!”
OOH! And Wow! I
thought.
Xylem and phloem!” Chloe
began gracefully. “A most
harmonious system flows through
each and every one of you! You
can’t have one without the other.”
Can’t have one without the
other! I pondered that thought.
Sort of a catchy phrase. I wonder
if it could be from a song my parents sang. I was brought back to the present as Chloe
50
continued singing and my neighbor tree moved to the side. I dropped onto my back
and saw a friendly face grinning at me from above.
“I’m sorry for moving. I wanted to get closer,” said my leaning tree. I grinned
back and hurried to my feet to move forward with the group.
“As I was saying, the xylem and phloem are so important, that if either quits
functioning or is damaged, we are in jeopardy of dying,” Chloe stated with such
intensity that everyone gasped in horror.
“How is that possible?” questioned my leaning tree.
Glancing around the assemblage, I saw a few brush tears away from their
furrowed bark with their smallest leaves.
Xylem and phloem”, Chloe explained, “are continuous systems that move water
and nutrients from roots to leaves and from leaves to roots. Water and nutrients are
absorbed by the tiniest root hairs and moved by the xylem very quickly, I might add
to the very tips of your leaves. Without water, our leaves wilt and die.”
Xylem moves water
and nutrients UP from
roots to leaves
51
“What about the nutrients?” A question popped up near my feet. I looked
down and there stood my three friends.
“I thought you had gone to hear someone else,” I quizzed.
“We decided it’s no fun without you,” Stormy replied with a grin.
“Excuse me!” Chloe interrupted, “Is there a question or are you holding your
own seminar!”
“We’re sorry! Yes, there was a question,” I slumped to the ground as Stormy
repeated his question. “What about the nutrients? You said without water, the leaves
would die. What do the nutrients do? “A fine question! You didn’t let that one pass
you by,” Chloe answered proudly.
I have noticed that the aged trees are particularly happy and proud when the
young ones are inquisitive. I scratched a careful note for my report.
“Nutrients are essential, too. Do you know how many there are?” Chloe
inquired while looking around at many sad faces. All eyes were evading Chloe’s gaze.
“I'm surprised and astounded!!” said Chloe. She swayed back and forth at the front of
the crowd, her huge canopy shaking sadly side to side. Moments passed eternally!
Quiet was interrupted by a quartet of trees moving from the crowd and merging to the
front. Everyone in the crowd looked at each other with great expressions of wonder.
“HMM. HMMM. HMMMMM. HMMMMMMM.”
“Nitrogen, potassium, phosphorus,
Macro-nutrients important to us.
But don’t forget calcium, sulfur, and zinc.
Without them we would surely sink.
Magnesium, manganese, boron, too,
Keep us growing gracefully through
Dry times and wet times and all in-betweens.
Micro-nutrients great -- If you know what we mean.
Copper and chlorine round out the pack
Of nutrients we do not wish to lack.
52
Oh, oh one is left. We forgot to bring
Mol-yb-de-num -- hard to say and harder to sing!”
Cheering erupted!! I had to admit that was quite a song and excellent
harmony. The quartet bowed and bowed; I thought they would surely crack.
Meanwhile Chloe stood to the side glowing. The four singers retreated to their
respective places amongst the pleased crowd. Branches, twigs, and leaves patted them
as they strode past. What a fun place! I looked at Stormy, Internode, and Thorny.
They were jiggling with delight. It took a few moments, but Chloe was able to begin
anew.
“Now those are the nutrients!” she said.
“But what do they do?” questioned a larger sapling off to my left.
“Everything!!” boomed Chloe. “All those nutrients are needed by our cells so
we grow taller, broader and healthier.”
Thorny held in his breath to puff out his trunk. Internode and Stormy
snickered.
Chloe continued, “Transpiration, photosynthesis, seed and fruit formation, root
growth, leaf drop, and wound closure, are just a few of the functions of these
incredible nutrients. All the processes that keep you alive are made possible by them.”
“Wow!” gasped the audience. Cheers erupted!
“We get most of them from the soil, but a small portion is taken in by our
leaves.” Chloe continued.
“Do we, or I mean, you, always have enough?” I stammered and felt my
cheeks redden.
“Our human friend is feeling like one of us!” Chloe laughed with the crowd.
“Actually there can be a problem on either side. If we get too much or too little of
one nutrient, it influences another nutrient which in turn affects all of our processes.
It’s a delicate balance. A harmonious balance, if you know what I mean!” Chloe
smiled and gestured to our quartet.
53
“Enough of the xylem.” she continued. “No! Wait! I forgot something
important. How could I have done that? My, my I must be getting old.”
“Maybe you need an extra nutrient!” one of the older burs in the crowd teased.
Chloe moved on with a wry smile cracking her bark.
“The xylem some is alive, but most is dead!”
Gasps roamed their way around the crowd, while everyone looked at
themselves carefully.
“I don’t feel dead,” responded an older bur.
“I know,” said Chloe, “and you shouldn’t feel that way, for the dead xylem
tissue is most vital. Human, come to the front, please,” Chloe asked.
I immediately looked around me and everyone laughed. Of course, Chloe
meant me. I was the only human in the grove. Trees patted me on the head as I
nervously worked my way through to the front. Little squirrels jumped from tree to
tree watching my progress. They were curious as to my being summoned to the front.
So was I.
“Human,” Chloe began, “What keeps you standing?”
“I don’t know; I guess my legs,” I stated with reservation.
“That’s partly true,” remarked Chloe, “But what else?”
I began to realize Chloe was trying to make a connection between what’s inside
me that helps me stand and what makes trees stand.
“Oh,” I said with sudden realization, “my skeleton keeps me standing!”
“That’s correct. And for trees to stand upright there must be something inside
as well. The dead xylem tissue keeps us standing.”
I remembered that the insides of trees are used by humans for lumber, but I
decided not to mention it. It didn’t seem an appropriate bit of information. A tiny
wiggling branch could be seen toward the back of the group. I recognized it as
Internode. “Chloe,” I said, “I believe someone is trying to get your attention.”
Chloe peered to the back and signaled for Internode to come ahead. Flanked
by my other two friends, they reluctantly moved forward. I chuckled for they bunched
together so tightly they looked like a bush striding forward with someone hiding
54
inside. Others chuckled too, watching the procession. Finally they made their
entrance.
Chloe waited and at length asked, “Did you have a question or were you
cooling off your leaves?”
Thorny stammered, “If the dead xylem helps us stand up, what does the living
xylem do?”
“Splendid question!” Chloe beamed. “Can anyone tell us?”
With that the “three-as-one” shuffled quickly to me. I sat cross-legged on the
ground at the front of the crowd expecting the answer momentarily as Thorny,
Internode, and Stormy tried to sit on my lap. The jostling and giggling caused a raised
eyebrow and downward glance from Chloe.
“You DO want to hear the answer DON’T you?”
We immediately ceased our revelry with silence! And more silence!
“Well,” said Chloe, “it appears some are lacking in their education. But that’s
WHY we are here!!”
Chloe seemed tickled at the prospect, and then began, “If we have a good year,
lots of rain, good soil, much warmth, etc., etc., etc.!...“Lots of nutrients flow through
the xylem, racing from the roots to our branches and our leaves,” continued Chloe.
“Ohhh! It is superb. We are well-supplied with our needs. But, what would happen if
we had too much? “
I grinned; I know what happened to Uncle Charlie. He got fat. “You store it
in the xylem!!” I yelled with such force that I lost my lap friends. Then I was
embarrassed! “Sorry,” I said.
Chloe rocked back and began to shake. I actually saw tears streak down her
bark. Then a huge laugh erupted from deep inside her. It became infectious.
Everyone joined in and slowly, I chuckled along. I guess my revelation surprised
everyone even me.
Once re-gaining control, Chloe stated, “Yes, that is exactly it. There are special
cells in the living xylem that store nutrients for later use. Not every year is a good one,
55
so when we are able, we store up for the future, much like our friend, the squirrel.”
Chloe pointed overhead.
I remembered Aesop’s fable of “The ant and the grasshopper”. The ant stored
food for later times, but the grasshopper didn’t. Then I thought of my savings
account. Hmmm. Make a note to check it when I return home.
“Now that is the xylem. What do you think the phloem does?” questioned
Chloe. “I’ll give you a hint. Remember, the xylem moves water and nutrients from the
soil to the leaves.”
“OOOOO!” A young sapling to our left was jumping up and down madly
waving branches.
“I believe someone wants to answer,” Chloe smiled at the group. “Go ahead!”
“Well, I think,” started the sapling, “if the xylem goes up, something has to
come down.”
“Good thinking, young one! Next question: what comes down in the phloem?”
“Hmmm,” the young sapling’s face twisted with considerable thought. It
looked from its base to its canopy and then back. And then it began the process again.
“I know!! If the xylem moves water and nutrients from the roots to the leaves, the
leaves must send something back to the roots!!!”
“Ahhh!! Exactly!!” Chloe stretched with pride. “When the sun hits your
leaves and mixes with water and carbon dioxide - thanks to our human,” Chloe bowed
toward me, “carbohydrate energy is produced. This energy flows downward in the
phloem and is deposited throughout our branches and roots. Without this process, our
roots won’t grow.”
“Remember,” she went on, “the dead xylem is deep inside us, but the living
xylem and phloem are very near the surface, right under our bark. This is very important
to remember! Damage to our bark, even very slight, has severe consequences to our
system.” Chloe’s gaze was directed toward the front row. I could be wrong, but I
swear Chloe was looking directly at me. I glanced from side to side and realized they
were all looking at me. Even my little pals were eyeing me strangely. I couldn’t help it,
I blurted out, “Did I do something?”
56
Chloe leaned toward me and said with an ominous hush, “It will be revealed to
you in time!”
“HMMMMM! HMMMMMMMMM!!! HMMMMMMMMMMMM!!
HMMMMMMMMMMMM!” Humming and swaying began, as the quartet entered
front stage. The quartet began to sing for it signaled the end of Chloe’s time.
Xylem and phloem
It all began
Running top to bottom
And back again.
Carrying water,
Nutrients, and en-er-gy
Important parts of me a Tree!”
The crowd dispersed repeating, “Xylem and Phloem………”
I picked myself up from the ground, stretched and sang, “Xylem and Phloem, da
da, da, da. Where shall we go now, gang?”
Waving branches assured me that they were directing me to hear another
adventurous story. I followed.
57
Chapter 8 - Flo’s Hospital Zone
Sobs, sniffles and sighs seemed out of place amidst the singing surrounding
Chloe’s tales. But I was sure I heard them. I shifted my body to get a fix on the
sounds. There they were again! More muffled sobs. Steering in the direction of the
ever increasing murmurs and pain-filled wails, I spotted a sparse group of burs along
the outer edge. Creeping closer, my pals and I listened intently. A soothing voice
among the sobs came from a short but very wide bur who talked like a nurse. "It
looks terrible, love! What happened?" A tender branch gently folded itself around the
trunk of the sad, sniffling tree.
“I was growing strong and healthy,” explained the sad sniffling tree, “shading
the house with great pride and joy. One day the man and two little ones ran outside.
The man carried something. I couldn't tell what it was. Suddenly, I was whacked on
this lower branch. OHHH!
OHHH!” The tree sobbed,
pointing to a thin and deformed
branch.
"There, there, love!” stated
Nurse Flo. “Let it out! Continue
whenever you want." A giant
branch gave a slight pat and tug of
embrace to the wailing tree.
Sniffles and wheezes were all that
could be heard for several
minutes. It was during this pause,
I realized this solemn and
reflective group was listening
intently to every word. The other
thing I noticed was their
saddened, furrowed bark faces, ragged parts, broken branches, stripped and torn bark,
58
and strange canopies. They looked like casualties crowding a hospital tent in the
aftermath of a war. My thoughts were drawn back to the object of our attention as the
sobbing died down to a few shudders.
"They were all laughing,” the sobbing tree resumed her story, “and I actually
loved their joy when a long, narrow vine-looking item gripped tightly around the bark
on my branch. The other end of the long thing appeared on my limb two feet from
the first vine-like thing. The man cinched them tightly around my branch and formed
a "U" shape just above the ground. He placed something in-between at the bottom of
the "U" -- such a curious ritual, I thought. Next, one of the little ones sat on the item,
the man pushed her and it began to swing back and forth. It didn't hurt much that
year, and they were having such fun, I didn’t even pay attention. But I did notice my
leaves at the end of that branch yellowed earlier than the rest of my leaves and then fell
off long before autumn.”
“The following year my leaves were worse,” continued the sobbing bur, “As I
grew, the rope tightened on my bark. Each year after that, my branch growth
decreased because, my xylem and phloem had been cut off. No carbohydrates moved from
my leaves and nothing came from my roots to the leaves. I was a mess; my branch
was starving.” Groans and gasps resounded from the gathering. A few more sniffles
flowed from the patient before he continued the sad tale. "Yes, my branch could no
longer receive water and nutrients from my roots. The leaves didn’t come back and
the branch died!" With this, the bur completely broke down. But the silent shaking of
the tree was far worse than the wailing. It was a sign of resignation that a once
beautiful, strong healthy branch was gone. The bur slowly lumbered away, shaking still.
An eerie quiet descended over the group like fog covering a beautiful valley
meadow. Within moments, tales of horror and emotion rolled from the audience like
an avalanche of snow billowing from the blue sky above the jagged Sierra Nevada
Mountains. One yellow-leafed, weak-voiced bur told of dogs being chained around
her trunk for several years. "The endless barking and circling my trunk with the chain
girdled me and drastically reduced my nutrients and carbohydrate flow by cutting
through the xylem and phloem," she explained with great sadness.
59
Another broke in among the responding wails to explain his unnatural-looking
canopy. "For decades, I grew majestically in hopes of being a national champion tree.
Then new people moved into my home. I thought I was developing beautifully. I
stretched with pride when they came outside to admire me. To my horror, they were
not happy with me. I heard my
people and another man say
things like, “Too Big! Branches
will fall on the roof! Too Old!
Probably over-mature.” OVER
MATURE!! The nerve!! I am
….or WAS in my prime."
She continued to describe
her disgrace when the man with a
chainsaw and a truck finished his
deed. “In one sweep of the man’s
buzzing, outstretched arm, a
branch on my left fell and then
another, and another were lopped
off. Haphazard hacking at my
canopy produced the hideous
result you see before you. I
nearly didn’t attend our gathering for fear of being ridiculed for my ugliness.”
A soulful, whispered wail swayed like a breeze across a prairie marsh. It
reached a crescendo that was frightening. I felt an increasing awkwardness, as I did
with the earlier pencil and paper episode, but this time I couldn't fix it. Apparently,
we, humans, do so much damage. I felt a heavy burden to right this wrong. Before I
could think of sealing my ideas of correction on paper, a young grotesque-looking
sapling arose to speak.
"Love? UH, what is it good for? Nothing! Absolutely Nothing!"
60
The phrase was vaguely
familiar, I mused. But before I
could place it, he spoke.
"Since I'm young, my
bark has not developed its
tough, corky layers. This makes
me a prime target for creative
Lovers’ ”, he stated in a
mocking tone.
"Couple after couple traipses
through my woods, listening for
snorting bucks. Not content
with that, however, they settle
themselves at the base of my
trunk, cooing and cuddling,
which leads to … CARVING!!
Yes, carving their undying love
in my precious, thin bark."
Wails gushed forth like the removal of your thumb from a leaking dam. Their
compassionate, rhythmic wailing brought chills to my body and salty tears to my eyes.
I was moved!
"Cutting into my bark, especially when it's thin and tender, causes the same
problems that girdling my trunk or branch would. The worst part is that nothing
happens quickly. "Wouldn't that be funny," he said with a smirk. "If THEY damaged
us and we immediately died. Like fell in their laps!"
Bouts of raucous laughter bounded across the crowd as the injured group
pictured the response to their demise after being damaged by humans. I had to laugh
myself, but I did wonder what prevents the tree from dying right away. Someone was
obviously reading my brain waves for the next voice asked just that.
61
"Why don't we die immediately when we’re damaged?" asked a soft voice next
to my leg. I looked down to see my buddies with Stormy’s branch held high. Dear Flo
had been standing quietly to the side, listening intently, but now began.
“Ah, my sweet loves! You have suffered greatly and I'm truly saddened by
these troubles! The answer to that question has to do with the way we are gloriously
made. Remember what Chloe said about reserves?” Several branches waved slowly.
I nodded with intensity and gathered Stormy, Internode, and Thorny close
around me. I did remember. This is what Chloe meant about me finding out about
damaging the phloem and xylem. Suddenly I felt so angry, the things human’s do.
“In good years, we store up reserves in our xylem,” continued Flo. “Then when
damage occurs, we use the reserves to protect ourselves. If damage occurs over and
over and over, we can’t store enough reserves and we weaken and eventually die.”
I jumped up, knocking my pals over. “I’m sorry, I’m sorry. I’ll do what I can
to stop these terrible things from happening to you!” Flo lumbered over to me and
with her entire canopy embraced me. Thorny, Internode, and Stormy wrapped
themselves around my legs. After some time, I moved away from Flo and headed away
from the crowd. I could see wet stains flowing down their furrowed bark. I kept
repeating, “I’m sorry, I’m sorry.”
I needed to move on to think about what I had just experienced. As I plodded
away, I heard strange noises, strange, because they were the sounds of laughter. I tried
to walk away from the happiness, but I was drawn toward it.
62
Chapter 9 -B
eginnings
I recognized the laughter now as the happy, chortling sounds of OOOHs and
AAAHs.
“OH, isn’t that the sweetest thing you’ve ever seen,” cooed a young sapling.
“I don’t think it was here yesterday. W-when do you suppose it broke through
the ground?” questioned a larger bur.
“We must be careful to protect it,” another bur added excitedly.
“Humph, ground-rats, moss sweepers!” grumped an ageing oak behind me.
Ignoring the ageing oak, a young sapling pointed to the ground and squeaked,
“How did it get there, Darla?”
A branch carefully and gently wrapped around the curious extended twig and
Darla began, “It’s a miracle, Da-a-rling. Let me explain.”
I worked my way toward the focus of their attention.
“Watch out!” shrieked a few voices. I stopped in mid-step and realized I was
about to tread on a green spot nearly hidden amid the bare soil. From my vantage
point, that’s all it looked like. Then it began to squirm and move from side to side. I
dropped to all fours, my pals scrambling with me. I smiled up and said, “Thanks for
the warning!” I saw two leaves, very small, but they were definitely bur oak. I was
beginning to recognize them now. I remembered Lobelia’s leaf tales.
Darla settled the gathering into a small, informal circle around this tiny miracle
in the soil. Darla, I learned, was from the southern range, which I suspected, for her
drawl had that soothing, magical melody I had heard while I was covering the southern
route of the Presidential primary in Tennessee.
I sat on the ground and leaned back against Charlie, a large bur. Getting
comfortable, I glanced up to see a pleasant smile crack on his thick bark. With a little
wink, he brushed the air with his giant branch and a cool breeze blew across my face.
It was very soothing awaiting the upcoming wonderful story. I wasn’t surprised in the
next instant to see Stormy wriggling through the crowd and curling up into my lap,
much like my dog Maxx. It felt good and homey. I closed my eyes for an instant,
63
thinking that Maxx would be having a grand time with all these trees. I chuckled at the
thought.
Darla’s pleasing drawl permeated the air. “How did this dainty, precious, two-
leaf seedling arrived at such a grand time in our history - you wonder??” she chuckled.
“The beautiful flower is where it
begins.”
Slowly, golden-yellow, curly,
whiffs floated through the air above
us.
“What’s that?” shouted
excited onlookers.
“Show off!” blurted my
neighbor.
I was confused about all this
yellow stuff. On another
assignment in North Carolina, I had
seen a similar yellow, powdery
substance dropping in layers all over
yards, houses, and cars. I never
found out what it was.
“Da-a-arlings!” said Darla.
“Don’t be alarmed. It’s a special
time and it happens to all of us.
Without it, our generations would
not continue. What you see
suspended above you is pollen,
thousands, maybe millions of very
fine grains of pollen. It comes from those male flowers or catkins that Joseph spoke
about.”
“How does it get out here?” asked Thorny.
64
“Foo, Foo, Fooooo,” repeated Darla. “Do what I do everyone. Foo, Foo,
Foooooo,” she continued.
Quizzical faces turned side-to-side, each searching for an answer.
“I believe she’s gone daffy!” chortled one bur behind me.
Darla encouraged us all and slowly, “Foo, Foo, Foooooo’s”, began erupting
across the audience. Once we got used to it, it was fun, but I still didn’t understand
why.
“Look, the yellow sky is moving!” shouted an excited young bur.
“Excellent!” exclaimed Darla.
“What ARE we doing?” I asked. “And what is the purpose of this pollen in
nature? Don't new oak trees sprout when squirrels bury acorns and forget about
them? What do these millions of particles of oak pollen dust do for oak trees or any
newly-sprouted oak seedlings?”
“OHHHH! DAAARLING, DAAAARLING! How sweet of you to ask?”
Darla responded. “You are Ab-So-Lute-Ly correct about the acorns. When squirrels
bury them, new oak trees sprout.” As if on cue, two squirrels raced up a large tree near
the front and jumped from branch to branch, and tree to tree, finally flinging
themselves to the ground behind me. Twitters of giggles bounced with them as each
tree responded to their tiny feet and tails rustling through the limbs.
“How charming!!” quipped Darla. “But where was I? Oh yes, pollen! The
wonderful thing about nature is that without the pollen, no acorns. No acorns means,
no more trees. This tiny young one that you see before you would not be here and our
species would quickly evaporate.” Sad faces and crinkling of bark were evident as the
group pondered that possibility. “Ah, but don’t fear. The process continues“, Darla
mused as she bent down to look at the tiny seedling. Her pause lingered for a long
time.
Finally Stormy spoke up. “Well, what is it called and how does it happen?”
“Oh, you want to know more?” Darla said glowing..
Cheers of agreement were heard from every corner.
65
“Well,” she began as she sauntered across the front and whisked her giant
branches from side to side, like a southern belle promenading in the parlor.
“Pollination is what happens. Every tree has flowers, even if you can’t see
them. Ours ARE very small.”
Much rustling was
heard as trees began to
explore themselves.
“Ooh, Ooh, Ooh!! I
think I found one,” an excited
youngster pointed at an elder
bur to its right, “It’s drooping.
Is it dead?”
“NO, NO!” Darla
responded with pleasure. “I
will explain. Some trees have
perfect flowers, meaning that
both male, called staminate, and
female called pistillate parts are
in the same flower. We
BURS, however, have
imperfect flowers. There are
both male and female flowers
on the same tree, but on different parts of the tree. The droopy grouping of flowers is
the staminate flowers and it is called a catkin. The female flower eventually becomes
the acorn.”
“Imperfect!” grumped an old tree. “Why I never heard such rubbish. I am
quite perfect!!”
Darla, overhearing the comment, explained, “Imperfect is just a way of
explaining that burs have two types of flowers, male and female, on the same tree.
You know, we need both flowers to produce acorns. It is still a perfect system.”
66
“I knew I would like this talk!” Stormy chuckled while tickling me in the rib
with his tiny limb.
I laughed, “Yes, it sounds like the birds and bees to me.”
Darla shot a look our way and we tried to shrink out of sight.
“As I was saying, and I know Joseph talked of this, some trees have only male
flowers or only female flowers. Our cousins, ginkgo, ash, and holly, are like this. They
are dioecious, which means ‘two houses’. It takes two trees for fruit to form. And only
the tree with the female flowers produces the fruit.
”Isn’t nature MARRRVELOUS!!” sang Darla. “AHHHHHH!”
“Back to us, and our
brother and sister oaks, we are
monecious, as Joseph
mentioned, is a fancy word
for ‘one house’. We have
male and female flowers on
the same tree. It doesn’t take
two trees to produce an acorn.
The staminate, or male
flowers as I mentioned
before, produce pollen which
then lands onto the female flower.”
“Wow, I can’t wait till I can do that!” shouted Stormy. “But why were we
making all that noise earlier, all that Foo Fooo stuff?”
“Perfect question, little one! You will become a storyteller someday, I just
know it!”
Stormy puffed his branches and settled in for more answers.
“The wind moves the pollen from one oak tree to another,” Darla continued.
That’s why we produce enormous amounts of pollen. It’s critical to producing future
bur oaks that are strong and long-lived. The pollen finds a female flower and the acorn
begins. Without the pollen and the wind, the acorn would not exist.”
67
About then, something hard hit my head. I thought it was one of my friends
playing another joke, but then I saw the object roll around at my feet. I bent down to
pick it up and another hit my back. I looked up to see more of these round objects
hanging from one of the elder burs right over my head. That’s when I noticed the
chuckling and shaking of his limbs.
“Very funny,” I stated. “What are these?”
“Acorns, darling!” Darla stated. “Baby oaks at your fingertips.”
I examined the acorn with my reporter’s eyes. It was quite large, nearly
covering my palm. There was a top and a bottom. An elder bur next to me said, “The
top is called a cap, and it covers the top the acorn. Did you attend Cork’s talk about
buds?” she questioned.
“Yes, I did, but what has that to do with acorns?”
“Take a good look at the cap,” she stated.
“Hey, there are lots of hairy projections on the acorn cap. They look like the
projections on the terminal bud.” I said. I also noticed that the cap was real bumpy.
“It’s one of the largest acorns in the oak family,” she informed me.
“Oh, oh, something’s happening.” Darla moved away from our group to join
other massive oaks passing behind us. I sensed our time here was complete.
Movement was beginning at every corner of the grove.
“What’s happening, Darla?” I asked as my three friends stayed close to my
legs.
She motioned for us to follow a line that was forming beside a small patch of
trees. Darla waited for me and pointed toward the edge of the forest patch. “Another
beginning,” she stated. “See the log on the ground?”
I nodded, but was unsure what was meant by a beginning. All I could see was
a rotting log. I wondered why the owner of the forest hadn’t cleaned up the mess.
“What do you mean ‘beginning’? My grandfather would have moved that old log out
of the woods long time ago.”
“Many humans are unaware of the importance of a fallen tree,” Darla
explained. “It fulfills an important mission. Our death brings life to the forest.
68
Nutrients remain in us and when we die, we become a fertile field for new trees a
beginning. Look closely; you young ones, too!”
My friends and I knelt close to the fallen log. That’s when I noticed the
solemnity of the passing line of burs. As they passed this log and others, they lowered
their canopies. I heard Thorny, Stormy, and Internode with hushed voices murmuring
amongst themselves. “It ends and begins here,” they said. I was understanding, and
without thinking reached out for the bits and pieces of the log. Gasps wafted from the
burs behind me. Darla quickly calmed everyone. “It’s all right. It’s the only way for the
human to learn.”
I looked toward Darla as she nodded, “Go ahead. What do you feel?”
I picked up the dark, cool fragments below the log. “Soil!” I exclaimed. “The log has
turned to soil.” I examined the soil closely and continued to move items around. I
spotted lots of little wiggling and crawling creatures, mushrooms, and then I spotted it.
Another tiny bur with its roots firmly planted in the newly-made soil.
“It’s the end and then the beginning. A circle of life,” Darla stated as she laid a
branch on my shoulder. I rose up to see Papa Root, Lobelia, Joseph, Flo, Chloe and
Ashley Oak beaming and waving as they lumbered off in various directions.
69
“Where are they going?” I asked.
“Dispersing throughout our range, going back for another year to spread our
story to all who will listen,” Darla stated as she moved south with another small group
of burs.
“But, I have so much to learn.”
“Next year! Come back!” Ashley called as she headed east.
I looked down at my friends. Tears ran through their little bark fissures. I was
full of new knowledge and ready to report, but I felt empty knowing we were
dispersing. I sat on the ground and opened my lap for my tiny little friends. We
leaned against the log with Internode fanning me with his tiny oak leaves. I closed my
eyes and felt the cool breeze. A tear trickled down my cheek, and I squeezed my
friends closer. The breezes grew faster and my tears flowed.
“Hey, hey, are you all right?” a voice from the past shouted. “Wake up! You’re
going to get soaked. Where are you from? Don’t you know when to come in out of
the rain?” he snickered. I looked up to see someone in a uniform. It was the ranger
who gave me directions to Bur Oak. I blinked, jumped up, and looked all around.
“Where did they go?” I asked.
“Who? I didn’t see anyone when I drove up. Are you sure you’re OK? Did
you fall and hit your head?”
“I – I, yes, I’m all right. I was looking for Bur Oak.”
The ranger laughed and headed for his green truck. “I think you found it as he
pointed to a small twig lodged between my windshield wiper and the window. As I
stumbled toward the door of my jeep, I saw the obtuse, tawny twig with hairy projections
surrounding the clustered terminal buds.
“I DO think you found it, “he chuckled.”
I tucked the twig in my pocket and glanced around the horizon to see small
dust cyclones forming in every direction.
I turned back to find the ranger and his green truck gone.

resemblance of poser to. Wow! Complicated is language!! (5)
Decomposition is the decay or breakdown of things into more basic elements. For
example, after a plant dies, it decomposes into organic nutrients. (1) Check origin of the
ending.
Dioecious is Greek for “two households” meaning one plant has male (staminate)

(5)
Fungus (plural fungi) are organisms that obtain energy by breaking down dead organic
material and that produce spores. Some fungi include mushrooms, toadstools, slime
molds, yeast, penicillium mold, and mildew. Classification: kingdom Fungus. (1) Word
origin is from 1520-30; Latin: fungus, mushroom; perhaps akin to Greek spóngos, sphóngos sponge.

Latin internodium inter (between) and node (knot) from Latin 1565-75. (5)
Latewood (late wood or summerwood) is the part of the wood in a growth ring of a
tree that is produced later in the growing season. The cells of late wood are smaller and
have thicker cell walls than those produced earlier in the season. Within a growth ring,
the change of early wood to late wood is gradual, but each layer of early wood from
73
the next growing season makes an abrupt contrast with the late wood before it, thus
leading to the perception of rings. (2) Word origin is from 1925-30. (5)
A leaf is an outgrowth of a plant that grows from a node in the stem. Most leaves are
flat and contain chloroplasts; their main function is to make food energy through
photosynthesis. The first leaf to grow from a seed is called the cotyledon.(1) Word origin
is before 900; Middle English leef, lef, Old English lēaf; cognate with Dutch loof, German Laub,
Old Norse lauf, Gothic laufs. (5)
A lobed leaf is one in which the margin is divided into rounded or pointed sections
and the incisions (cuts) go less than halfway to the midrib. (1) Word originates from 1515-
25; Medieval Latin lobus (Late Latin: hull, husk, pod); Greek lobós, akin to Latin legula lobe of
the ear. (5)
Margins of a leaf are its edges, which vary from plant to plant. The margins can be
smooth, serrated, or toothed; they can also be lobed or entire. (1) Word originates from
1300-50; Middle English; Latin margin- (stem of margō) border; akin to march. (5)
Monecious plants have the male (pistillate) and female (staminate) reproductive organs
on the same plant, such as oaks. (1) Word origin is 18 century from New Latin monoecia, from
mono- (meaning one) + Greek oikos house. (5)
Mushrooms are fast-growing fungi (they are not plants). They grow in dark, damp
places and reproduce via spores. (1) Word origin is from 1350-1400; alteration (by folk
etymology) of Middle English muscheron, musseroun; Middle French mousseron; Late Latin
mussiriōn-, stem of mussiriō. Now you can look up the origin of those other words. (5)
Mycorrhiza is a fungus that grows in a symbiotic relationship with the roots (or
rhizoids) of a plant. (1) Word origin is from 1890-95; myco- + -rrhiza. Another compound word
for you to look up. (5)
A node is the point on a stem where a leaf is attached or has been attached; a joint. (2)
Word originates from 1565-75; and is Latin nōdus for knot. (5)
A nutrient is a chemical that an organism need to ingest in order to survive (like fats,
carbohydrates, vitamins, minerals, etc.). (1) Word origin is 1640-50; Latin nūtrient- (stem of
nūtriēns), present participle of nūtrīre to feed, nourish; see –ent. (5)
Obovate is a leaf or similar flat part shaped like the longitudinal section of an egg with
the narrower end at the base; inversely ovate. (3) Word origin is 1775-85; ob- a prefix
meaning “toward,” “to,” “on,” “over,” “against,” originally occurring in loanwords from Latin, but
now used also, with the sense of “reversely,” “inversely,” to form Neo-Latin and English scientific
terms: object; obligate; oblanceolate.+ ovate meaning from 1750-60; Latin ōvātus, equivalent to ōv
(um) egg+ -ātus –ate. (5)
74
Obtuse is a blunt or rounded at the apex, the converging edges separated by an angle
greater than 90 degrees. (4) Interesting origin and history of the term - Early 15c., "dull,
blunted," from Middle French obtus (fem. obtuse), from Latin obtusus "blunted, dull," also used
figuratively, past participle of obtundere "to beat against, make dull," from ob "against" (see ob- ) +
tundere "to beat," from PIE *(s)tud-e- "to beat, strike, push, thrust," from root *(s)teu- "to push,
stick, knock, beat" (cf. Latin tudes "hammer," Sanskrit tudati "he thrusts"). Sense of "stupid" is
first found c.1500. Related: Obtusely; obtuseness. Which do you think is associated with our term?
An organelle is a membrane-bound structure within a plant's cell (and all eukaryotic
cells) where specialized metabolic tasks occur. Some organelles include the nucleus,
nucleolus, mitochondria, the ER (endoplamic reticulum), and lysosomes. (1) Word
origin is 1905-10; New Latin organella, diminutive of Latin organum organ; see elle. (5)
A perfect flower has both male (stamen) and female (ovary) reproductive organs on
the same flower. (1) Word origin for flower - 1150-1200; Middle English flour flower, best of
anything < Old French flor, flour, flur < Latin flōr- (stem of flōs). Cf. blossom; Origin of stamen -
1640-50; Latin stāmen warp in upright loom, thread, filament, equivalent to stā (re) to stand + -
men noun suffix; akin to Greek stmōn warp, Sanskrit sthāman place. Origin of ovary - 1650-60;
< New Latin ōvārium. See ovum, -ary. (5)
A petiole is a leaf stalk. On a compound leaf, the petiole extends from the stem to the
first set of leaflets. A leaf without a petiole is sessile. (1) Petiole word origin is 1745-55; <
