macrocarpa is a subspecies of tree of the family Oleaceae.

Like the related species Olea welwitschii, it grows in sandy desert regions of Kenya, Tanzania and Uganda.

Both these species are sources of firewood, but the wood is also valued for its prominent veins, similar to that of the European olive though finer in texture.

[2] As hardwoods they are considered suitable for flooring, furniture, carving, turning and veneers.

[3] The leaves have been used in folk medicine as an antibacterial, a property which has found some support in the laboratory.
