About

Plukenetia conophora, also called Nigerian walnut, and conophore, is a climbing shrub in the genus Plukenetia. It is not related to the walnut, being so named because its nuts bear a superficial resemblance to the walnut. It is native to tropical western and central Africa from Togo to Congo and in Sierra Leone. It is abundant in the Nigeria, Cameroon, Republic of the Congo and Democratic Republic of Congo. It prefers rain-forest hedge in half-shady places; low bush; secondary forest; plantations at elevations from 250–1,400 m (820–4,590 ft). Although it is well recorded in Sierra Leone, it is apparently not indigenous to Sierra Leone, since it is not recorded in Liberia and Ghana. Its presence in Sierra Leone is due to returning slaves for it is known to the Krio by its Yoruba (Nigerian) name. Plukenetia conophora is the only Plukenetia species native to West Africa or Central Africa.
