This is a popular species among collectors and the population has declined substantially in the past 90 years (3 generations). The subpopulation on Mananga mountain has been particularly affected by collecting. It qualifies as Endangered due the extent of past decline and its narrow distribution range. Some authors regard the true E. lebomboensis as having a narrower distribution, which if correct, would result in a classification of Critically Endangered.

Geographic Range [top]

Range Description:This species occurs in the upper reaches of the Pongola and Bivane rivers in northern KwaZulu-Natal province and in the Mananga area of eastern Mpumalanga province, South Africa. Plants are also found in the adjacent area of Mozambique and along the northern parts of the Lebombo mountains of Swaziland. There is some debate about the actual range of E. lebomboensis: the original description includes the plants in the Bivane area of KwaZulu-Natal, but P.J.H. Hurter argues that only the plants in northern Swaziland and the Mananga region of Mpumalanga are true E. lebomboensis. Recorded to occur at altitudes ranging from 500 to 1,000 m asl.
Countries occurrence:
Mozambique; South Africa (KwaZulu-Natal, Mpumalanga); Swaziland
