Securidaca longipedunculata (Violet tree, Afrikaans: Krinkhout, Bambara: Satene, Tswana: Mmaba, Venda: Mpesu) is a species of tree in the Securidaca genus. It is most commonly found in the tropical and subtropical areas of Africa, and it was given protected status in South Africa. The generic name is derived from Latin securis, as the shape of the wing on the nut recalls a hatchet. The specific name longipedunculata hints at the long peduncle on which the flowers are borne.
