I came across this one in a book today and thought I'd share. As much for the definition as for anything else.

Drupe -

an indehiscent fruit consisting of outer epicarp, fleshy or fibrous mesocarp, and stony endocarp enclosing a single seed, as in the peach, plum, and cherry

There is also a diminutive form, druplet:

a little drupe, as one of the individual pericarps composing the blackberry.

I'll leave it for you to look up pericarp.

Hope you like it.

Not too useful for me. Sorry.
