Justification
A rare, range-restricted species (EOO 231 km² and AOO<36 km²), known from six locations. Adapted to a rare and very specialized habitat on mineral-rich serpentine soils. Potentially threatened by mining but not declining at present.
Distribution

Habitat and Ecology

Major habitats
Grassland
Description
Steep, rocky slopes in grassland, restricted to serpentine soils.
Threats
Potentially threatened by alien encroachment, there are wattles near the edge of at least one known subpopulation. Serpentine soils are rich in minerals and the range of this species is dotted by disused mining sites. A renewed interest in mining in the area could pose a potential threat of further habitat loss. Because this is a rare, range restricted species that is not widely available in cultivation (according to Van Wyk and Smith 1996 it is hard to cultivate) it may also be targeted by succulent collectors.
