Drupe

drupe \ˈdrüp\ noun: a one-seeded indehiscent fruit having a hard bony endocarp, a fleshy mesocarp and a thin exocarp that is flexible (as in the cherry) or dry and almost leathery (as in the almond)

Etymology: New Latin drupa, from Latin, overripe olive, from Greek dryppa olive

Joyce Kilmer’s lost opportunity: “I think that there is no such fruit / As leath’ry as the almond drupe.”
