Epigynous berry

In botanical terminology, a berry is a fleshy fruit without a stone produced from a single flower containing one ovary. Berries so defined include grapes, currants, and tomatoes, as well as cucumbers, eggplants (aubergines) and bananas, but exclude certain fruits commonly called berries, such as strawberries and raspberries. The berry is the most common type of fleshy fruit in which the entire outer layer of the ovary wall ripens into a potentially edible "pericarp". Berries may be formed from one or more carpels from the same flower (i.e. from a simple or a compound ovary). The seeds are usually embedded in the fleshy interior of the ovary, but there are some non-fleshy exceptions, such as peppers, with air rather than pulp around their seeds.

Many berries are edible, but others, such as the fruits of the potato and the deadly nightshade, are poisonous to humans. Some berries, such as the white and red mulberry, are poisonous when unripe, but are edible in their ripe form.

A plant that bears berries is said to be bacciferous or baccate (a fruit that resembles a berry, whether it actually is a berry or not, can also be called "baccate").

In everyday English, "berry" is a term for any small edible fruit. Berries are usually juicy, round, brightly coloured, sweet or sour, and do not have a stone or pit, although many pips or seeds may be present.
