Justification | This species has an extent of occurrence (EOO) and area of occupancy (AOO) of 8 km², and is known from two locations. It is potentially threatened by livestock overgrazing and trampling, and is therefore listed as Vulnerable under criterion D. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape |

Major system | Terrestrial |
Major habitats | Hantam Plateau Dolerite Renosterveld |
Description | It occurs on dolerite outcrops in heavy red clay. |
Threats |
| This species has an extremely localised extent of occurrence and area of occupancy so a relatively minor local event could severely reduce the size of this population, and the species could become threatened with extinction. Overgrazing and trampling by livestock is a potential threat. |
