Justification | EOO 50 km², plants at two known locations continue to decline due to ongoing habitat degradation as a result of overgrazing. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape |
Range | Richtersveld, Cornellskop and Numees Mountain. |
Habitat and Ecology |
Major system | Terrestrial |

Threats |
| This species is threatened at both known locations by severe, ongoing habitat degradation due to overgrazing by livestock. |
Population |
This species was recently rediscovered at one of only two known localities in the Richtersveld, where it was last recorded in 1962. A small subpopulation of fewer than 100 mature individuals occurs on Cornells Kop. It also still occurs on the mountains above Numees Mine, where it is also localized (P.C.V. van Wyk pers. comm.).
