In botany, a drupe is an indehiscent fruit in which an outer fleshy part surrounds a single shell of hardened endocarp with a seed (kernel) inside. These fruits usually develop from a single carpel, and mostly from flowers with superior ovaries. The definitive characteristic of a drupe is that the hard, "lignified" stone is derived from the ovary wall of the flower—in an aggregate fruit composed of small, individual drupes, each individual is termed a drupelet and may together form a botanic berry.
