Justification | This highly range-restricted species, with an extent of occurrence (EOO) of less than 10 km², is known from a single site, but it is not threatened. It therefore qualifies for listing as Critically Rare nationally and qualifies under the IUCN 3.1. criteria as Least Concern. |
Distribution |
Endemism | South African endemic |

Threats |
| Slopes where the collections were made are not transformed, therefore, it is not suspected to be declining. |
Population |
The species has a highly localized distribution. It is known from two collections made in 1928 (Holotype) and 2001. Notes in a collection made by Helme (#2387 BOL) in 2001 indicate that plants were common on north east slopes. No population data are available but the population trend is suspected to be stable.
