Wikipedia definition
2. DrupeIn botany, a drupe is an indehiscent fruit in which an outer fleshy part surrounds a shell (the pit, stone, or pyrene) of hardened endocarp with a seed (kernel) inside. These fruits develop from a single carpel, and mostly from flowers with superior ovaries. The definitive characteristic of a drupe is that the hard, lignified stone (or pit) is derived from the ovary wall of the flower. In an aggregate fruit composed of small, individual drupes, each individual is termed a drupelet.
