Justification | A rare, range-restricted species known from one subpopulation, but not threatened. It is therefore listed globally as Least Concern and nationally as Rare. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape |
Range | This species is found in the Doring River Valley in the northern Ceres Karoo north of Swartruggens, in the Western Cape Province of South Africa. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Swartruggens Quartzite Karoo |
Description | It grows in deep sandy soils in Swartruggens Quartzite Karoo vegetation. |
Threats |
| This species' habitat, Swartruggens Quartzite Karoo, is still 90% intact, although parts of it is degraded due to overgrazing. No threats were observed at the type locality, currently the only known subpopulation. |
Population |
It is currently known from a single subpopulation from an area known for its several endemics. The area is remote and still relatively poorly explored, and it is likely that other, undiscovered subpopulations exist.
