The “olive family” contains trees or shrubs, and is distributed throughout the world, except for the Arctic; they are especially abundant in tropical and temperate Asia. Many members of this family have economic and aesthetic qualifications: the olive tree (Olea europaea L.) is the source of olive and olive oil; the “ash (Fraxinus L.)” is used to obtain hardwood timber; and species belonging to the genera “jasmine (Jasminum L.)”, “privet (Ligustrum L.)”, and “teaolive (Osmanthus Lour.)”are widely used as garden ornamental plants.
