Olea (/ˈoʊliə/ OH-lee-ə[3]) is a genus of flowering plants in the family Oleaceae. It includes 12 species native to warm temperate and tropical regions of the Middle East, southern Europe, Africa, southern Asia, and Australasia.[2] They are evergreen trees and shrubs, with small, opposite, entire leaves. The fruit is a drupe. Leaves of Olea contain trichosclereids.[4]

For humans, the most important and familiar species is by far the olive (Olea europaea), native to the Mediterranean region, Africa, southwest Asia, and the Himalayas,[5][6] which is the type species of the genus. The native olive (O. paniculata) is a larger tree, attaining a height of 15–18 m in the forests of Queensland, and yielding a hard and tough timber. The yet harder wood of the black ironwood O. capensis, an inhabitant of Natal, is important in South Africa.^[citation needed]

Olea species are used as food plants by the larvae of some Lepidoptera species including double-striped pug. ^[citation needed]
