>How is a walnut not a nut? I was taught--and teach--that the outer layer of a
>walnut is fused bracts, not pericarp, and that a walnut *is* a nut...
I was taught that the walnut is a drupe, but learned from Kramer's post,
also, that the origin of the husk is controversial, at least. Is the
coconut OK as a drupe, or is it, too, of nebulous certainty? And then we
could debate the grouping of avocado (which I teach as a one-seeded berry
rather than a drupe)!
