Major habitats
KwaZulu-Natal Hinterland Thornveld, Midlands Mistbelt Grassland, Dry Coast Hinterland Grassland, Southern KwaZulu-Natal Moist Grassland
Description
Mistbelt and Ngongoni grassland, 800-1300 m.
Threats
Very little of this species' grassland habitat remains intact after extensive losses to timber plantations, sugarcane, urban expansion, spreading rural settlements, and degradation due to overgrazing. Habitat loss to urban and industrial development continues around Pietermaritzburg. Remaining subpopulations are also threatened by competition from unmanaged alien invasive plants.
Population

In spite of extensive habitat loss and degradation, this species is still fairly common, occurring in numerous fragments on the outskirts of Pietermaritzburg (A. Young pers. comm.). It appears to be somewhat tolerant of disturbance. Subpopulations are however small, with field counts indicating around 10 plants per subpopulation, and it continues to decline due to ongoing habitat loss and degradation.
