Sclerosperma

Sclerosperma is a monoecious genus of flowering plant in the palm family found in Africa where three species are known. Having no obvious relatives, it does resemble the Madagascar native Marojejya though a detailed study of Madagascar's palms is required to determine if any true relationship exists. The lack of relatives, and its interesting qualities, indicate, at one time, the existence of a diverse African palm flora. The name is from two Greek words meaning "hard" and "seed".
