枝より幹 TRUNK not a branch

直径１．５メートルはあろうかと言うイチョウの大木。　幹の表面に顔みたいなものが二つ。　面白いと思っていたが、それより目立たず、もっと面白いのが、いきなり生える、1枚の葉っぱ…。　おい、葉っぱよ、なぜ枝に生えない！？
幹の中央、ちょっと下に葉っぱあり。
The almost 5 feet trunk of this ginkgo tree has two faces, which caught my eye.  But, as I approached to take a closer look, I was amaized to to see such a cute leaf.  Oh little leaf, why did you not chose a branch up in the ari, but this trunk, as your settling point?
The leaf is right in the center of the trunk, look down a little bit, its hard to see.
