Justification | This species occurs across a wide range and has an extent of occurrence (EOO) ranging between 20 000 km² and 179 745 km². It is known from six locations and is potentially threatened by livestock trampling, droughts and alien invasive species, but does not qualify for a threatened category. It is therefore assessed as Least Concern. |
Distribution |
Endemism | Not endemic to South Africa |
Provincial distribution | KwaZulu-Natal, Limpopo |
Range | It is widespread in southern Africa from Zambia and Botswana, southwards to Limpopo and eastern KwaZulu-Natal. |
