An endemic species to the Klein Roggeveld escarpment (extent of occurrence 84 km², and area of occupancy 16 km²). It is known from four locations. Some of the habitat has been transformed for crop cultivation in the past. Overgrazing by livestock and more frequent and persistent droughts are causing ongoing habitat degradation. This species therefore qualifies as Endangered under criterion B.

Habitat and Ecology
Major system
Major habitats
Koedoesberge-Moordenaars Karoo, Central Mountain Shale Renosterveld
Open karroid scrub on sandy clay alluvium.
Threatened at one of its locations (De Hoop farm) by loss of habitat in the past for wheat cultivation further ploughing remains a future threat. Grazing by livestock is a past, present and future threat to this palatable species, grazing pressure is intensifying as a result of persistent drought experienced in the region since 2016.

Recorded only from herbarium collections, there are no details on the size and trends of the population documented, however degradation of habitat is mentioned on herbarium specimens and is used to infer that the population is likely to be declining.
