Neutral victorengel On Feb 2, 2012, victorengel from Austin, TX wrote:

There's an interesting feature of the acorns I noticed this year. Normally, an acorn contains two cotyledons, joined by a common shoot. Q. germana acorns are not like this. They do seem to have two cotyledons, but each has its own sprout. The leaf end of the sprout is at the center by the proximal end of the acorn. The root emerges out of the side of the acorn, diagonally outward and distally from the leaf end.
