En botánica una drupa es un fruto monospermo de mesocarpo carnoso, coriáceo o fibroso que rodea un endocarpo leñoso (“carozo”, a veces llamado “hueso”) con una sola semilla en su interior. Estos frutos se desarrollan de un único carpelo y en su mayoría de flores con ovarios superos.

In botany, a drupe (or stone fruit) is an indehiscent fruit in which an outer fleshy part (exocarp, or skin; and mesocarp, or flesh) surrounds a shell (the pit, stone, or pyrene) of hardened endocarp with a seed (kernel) inside. These fruits usually develop from a single carpel, and mostly from flowers with superior ovaries (polypyrenous drupes are exceptions). 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 (such as a raspberry), each individual is termed a drupelet and may together form a botanic berry. Other fleshy fruits may have a stony enclosure that comes from the seed coat surrounding the seed, but such fruits are not drupes. Some flowering plants that produce drupes are coffee, jujube, mango, olive, most palms (including date, sabal, coconut and oil palms), pistachio, white sapote, and all members of the genus Prunus, including the almond (in which the mesocarp is somewhat leathery), apricot, cherry, damson, nectarine, peach, and plum. The term drupaceous is applied to a fruit which has the structure and texture of a drupe, but which does not precisely fit the definition of a drupe.
