Don, according to "Seeds of Woody Plants in North America" by James &
Cheryl Young, "the fruit is an elongated, chestnut-brown,
single-seeded achene with a hairy tuft at the base. The achenes,
with hairs removed, are used as seeds. The elongated embryo is
surrounded by a thin endosperm."
The photos show P. occidentalis, the American sycamore, - no size
given - as a very long, slender item, sharply pointed at one end and
rounded at the other, rather like a long thorn in shape. P.
racemosa, the California sycamore is shorter and thicker, but still
pointed at one end and rounded at the other. Both appear to be
rather flat with what looks like a slightly raised central vein.
Hard to tell in these pix, but they might have a slightly triangular
form.
There is also an illustration of a longitudinal section through an
achene in the book..hard to describe:-)
Hope this helps a tad..
