Oak
trees have the same unblushing approach to reproduction that characterizes the
plant world's expression of all necessary physical functions, including growth, nutrition,
birth and death. Green plants do the weirdest things, and you never see them sweat.
Oak trees, it turns out, fertilize themselves, having the necessary equipment for both male and
female functions. The botanical term for this overdetermined status, according
to the sources I have consulted, is "monoecious," an unpronounceable
word meaning they produce both male and female flowers.
So in the
spring, when a green plant's fancy turns to reproduction, oak trees produce male flowers called "staminate" and female flowers
called "pistillate," both on their own tree self. These flowers are such
modest tints of green, yellow and tan -- unlike the reds and hot pinks and orange and
lavender of shameless fruit trees resulting in events such as "cherry
blossom time," or the pure alba of the dogwoods -- that you hardly
know they are there.
Yet quietly
in the sturdy, straight-ahead manner characteristic of its kind, the oak gets
the job done. The male flowers "grow into a thin, wormlike shape known as
a catkin or an ament," according to my source (http://www.ehow.com/about_6465166_do-oak-trees-reproduce_.html).
There we
have it: "catkins," a word redolent of Victorian drawing classes and
a famous love scene in a once-shocking D.H. Lawrence novel called "Women in
Love."
That
'wormlike' shape has a certain masculine sneakiness to the sound of it. Sure
enough catkins consist of "stamens," the male flower part that releases the substance that
so troubles allergy sufferers int he spring: pollen. I now know
where to look for the cause of the many sneezes that have accompanied this year's early
growing season. I recall the word "stamen" as one of those
common "parts of a flower," now I know that stamens are in biological cahoots with
'catkins.'
OK. Stamens
give us pollen, which besides making people go red-eyed and sneezy, comes to
rest (according to my source) on "receptive stigma in the female flower."
That's pretty blunt.
But add
this: "with a little help from the wind." Ah, those pandering breezes
of spring.
So I now know why those light brownish wormlike organic somethings are all over my yard, a fresh supply of them every morning on the 'bistro' table where we breakfast in warm weather under the oak tree. I have been picking them off the upper leaves of plants, just because their pervasive accumulation dulls the color.
We're ready
to bring this indictment to a close now. The oak tree's female flower -- don't ask me what
they look like, but I know they're not long and stringy like catkins -- "grow where the leaf
stalks meet the branches or twigs." They are modest and unassuming, I
suppose, but in the end they conquer, and endure, hang around all summer, and
deliver the goods. Because by summer's end those "receptive stigma" grow into acorns. And here we are in
familiar territory.
How do
these acorns, that we step on on the sidewalk and make that satisfying crunchy
sound, come about? Now we know.
One last
term is introduced as our source informs us that acorns "sit in hard cups
called peduncles."
So do we all understand now why in a boom year like the current one we have brownish, yellowish tree detritus all over our yards?
Well I'll
be a monkey's peduncle.
What a delightful exposition. My wife and I thoroughly enjoyed your prose, and learned something to boot!
