The ancient word of the Day is venation. This is a delicate and diaphanous pattern of veins appearing on the blade of a leaf.
These delicate patterns are most visible in autumn as decay befalls the forest floor and the wind crumbles away the leaf litter leaving behind the frail leaf filigree, a ghost echo of summer’s full flush.
Venation may be reticulate, palmate, arcuate in form depending on the structure of the plant and how it grows.
Learning the Trees by Howard Nemerov
Before you can learn the trees, you have to learn
The language of the trees. That’s done indoors,
Out of a book, which now you think of it
Is one of the transformations of a tree.
The words themselves are a delight to learn,
You might be in a foreign land of terms
Like samara, capsule, drupe, legume and pome,
Where bark is papery, plated, warty or smooth.
But best of all are the words that shape the leaves—
Orbicular, cordate, cleft and reniform—
And their venation—palmate and parallel—
And tips—acute, truncate, auriculate.
Sufficiently provided, you may now
Go forth to the forests and the shady streets
To see how the chaos of experience
Answers to catalogue and category.
Confusedly. The leaves of a single tree
May differ among themselves more than they do
From other species, so you have to find,
All blandly says the book, “an average leaf.”
Example, the catalpa in the book
Sprays out its leaves in whorls of three
Around the stem; the one in front of you
But rarely does, or somewhat, or almost;
Maybe it’s not catalpa? Dreadful doubt.
It may be weeks before you see an elm
Fanlike in form, a spruce that pyramids,
A sweetgum spiring up in steeple shape.
Still, pedetemtim as Lucretius says,
Little by little, you do start to learn;
And learn as well, maybe, what language does
And how it does it, cutting across the world
Not always at the joints, competing with
Experience while cooperating with
Experience, and keeping an obstinate
Intransigence, uncanny, of its own.
Think finally about the secret will
Pretending obedience to Nature, but
Invidiously distinguishing everywhere,
Dividing up the world to conquer it,
And think also how funny knowledge is:
You may succeed in learning many trees
And calling off their names as you go by,
But their comprehensive silence stays the same.
John Bate: The Mysteryes of Nature and Art
Bi-Focal by William Stafford
As fire burns the leaf
and out of the green appears
the vein in the center line
and the legend veins under there,
So, the world happens twice—
once what we see it as;
second it legends itself
deep, the way it is.
