Encephalartos altensteinii is a species of cycad in the family Zamiaceae. It is native to the eastern Cape Province of South Africa. This species is named after the German botanist Karl August von Altenstein.

Description[edit | edit source]

Encephalartos altensteinii is a medium-sized cycad that can grow up to 6 meters in height. The trunk is typically unbranched and covered with persistent leaf bases. The leaves are pinnate, dark green, and can reach lengths of up to 3 meters. Each leaf consists of numerous leaflets that are arranged in a V-shape along the central rachis.

Reproduction[edit | edit source]

This species is dioecious, meaning that individual plants are either male or female. Male plants produce large, cylindrical cones that can be up to 50 cm long, while female plants produce slightly larger, barrel-shaped cones. Pollination is typically carried out by insects, and seeds are dispersed by animals.

Conservation Status[edit | edit source]

The species is listed as Vulnerable on the IUCN Red List due to habitat loss and over-collection. Conservation efforts are in place to protect its natural habitat and to propagate the species in botanical gardens.

Uses[edit | edit source]

Encephalartos altensteinii is often used as an ornamental plant in gardens and landscapes. It is valued for its striking appearance and its ability to withstand a variety of environmental conditions.
