(olive; family Oleaceae)
A genus of about 20 species of trees and shrubs in which the leaves are usually grey-green and elliptical or linear, and the fruits are berries rich in oil. They are widely distributed in the Old World. O. europaea (common olive) is much cultivated in Mediterranean climates for its fruits, for eating, and for olive-oil production, but its native home is probably Africa.
