About

Encephalartos lebomboensis is a species of cycad in the family Zamiaceae. Native to the Lebombo Mountains of South Africa, the species was first described in 1949 by the South African botanist Inez Verdoorn. It is commonly known as the Lebombo cycad, although the name is also used for Encephalartos senticosus which also occurs in the same locality.

Where it grows

Encephalartos lebomboensis has two separate populations, one in the vicinity of Mananga in Mpumalanga province in South Africa and a southern population centred on Piet Retiefion in the upper Pongola River Valley. It is a very rare and endangered species and grows in sunny positions on cliffs and steep, rocky slopes among sparse vegetation. This region has hot, fairly wet summers and cool, dry winters with frequent mists. It is also native to Mozambique and Eswatini.
