A simple fruit derived from a single carpel. A drupe usually contains a single seed enclosed by a hardened endocarp, which often adheres closely to the seed within. In peaches, plums, cherries, and olives, a fleshy edible mesocarp surrounds the endocarp (the pit or stone). In the coconut, a fibrous mesocarp (the husk) surrounds the endocarp (the shell), while the white edible portion is the endosperm. Compare berry, pome.
