Justification | This species is widespread and common and has an extent of occurrence (EOO) of 223 621 km². It is known from more than 30 subpopulations and is therefore assessed as Least Concern as it is too abundant to be at risk of extinction in the near future, however the population trends should be monitored. |
Distribution |
Endemism | Not endemic to South Africa |
Provincial distribution | Eastern Cape, Free State, KwaZulu-Natal, Mpumalanga |
Range | This species' distribution extends along the eastern seaboard and interior of South Africa, from Port Elizabeth in Eastern Cape through KwaZulu-Natal and north-eastern Free State to Wakkerstroom in Mpumalanga. It can also be found in southern Eswatini. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Grassland |
Description | It occurs in stony grassland, from near sea level inland to the foothills of the Drakensberg, usually on dolerite or sandstone soils. |
Threats |
| It is threatened by habitat degradation due to agriculture (livestock grazing) and too irregular fires. Some of the subpopulations are threatened by competition from spreading, unmanaged alien invasive plants and harvesting for the medicinal trade. |
Population |
This species is known from many historical collections, and between 2010 and 2023, citizen scientists on the iNaturalist platform have posted 120 observations across its known range. From these observations, we can infer that the population is locally common, stable, and not declining.
