About
Encephalartos altensteinii is a species of palm-like cycad in the family Zamiaceae. It is endemic to South Africa. The species name altensteinii commemorates Altenstein, a 19th-century German chancellor and patron of science. It is commonly known as the breadtree, broodboom, Eastern Cape giant cycad or uJobane (Zulu). It is listed as vulnerable due to habitat destruction, use for traditional medicine and removal by collectors.
Where it grows
This species is widespread in the Eastern Cape and south-western KwaZulu-Natal provinces of South Africa. It favours sites near the coast including open scrub, steep rocky slopes, evergreen forests in valleys and river banks. It also occurs inland at a higher altitude in isolated sites in the Amatola Mountains.
