A range-restricted taxon (EOO 1017 km²), known from six to eight locations and declining due to ongoing habitat loss and degradation.
Distribution
Endemism
South African endemic
Provincial distribution
Eastern Cape, Western Cape

Rocky slopes in renosterveld and lower sandstone slopes.
Threats
The most severe threat to this taxon is ongoing habitat loss and fragmentation due to ongoing agricultural expansion. In addition, remaining fragments also continue to be degraded to overgrazing.
Population

This taxon is poorly known and rarely collected, but may also be overlooked. Historical records indicate that it occurs at between six and eight locations, and continuing population decline is inferred from ongoing habitat loss to agricultural expansion at most known locations.


Population trend
Decreasing
