Encephalartos (Bread Palms) Lehm. 1834
plant genus in the zamiaceae family
Encephalartos is a genus of cycad native to Africa. Several species of Encephalartos are commonly referred to as bread trees, bread palms or kaffir bread, since a bread-like starchy food can be prepared from the centre of the stem. The genus name is derived from Ancient Greek ἐγκέφαλος (encéphalos), meaning "head", and ἄρτος (ártos), meaning "bread", referring to the use of the pith to make food. They are, in evolutionary terms, some of the most primitive living gymnosperms. All the species are endangered, some critically, due to their exploitation by collectors and traditional medicine
