Description
Deep sandy soils derived from granitic gneiss on mountain slopes and rocky outcrops, 260-1500 m.
Threats
There are no severe threats to this species. Within its range, the main land use is livestock grazing, and in some areas the natural vegetation has been degraded due to overgrazing and trampling where rangelands have been overstocked. This species is however not grazed, and appears to be resilient to disturbance, as subpopulations tend to be large even in very disturbed areas.
Population

This species is widespread and common. Subpopulations are large, and it persists even in heavily overgrazed communal rangelands in the Kamiesberg. As there are no severe threats to this species, the population is not suspected to be declining.
