D. Raimondo & L. von Staden
A localized habitat specialist, known from one location and potentially threatened by overgrazing and collection of plants from the wild for the succulent trade.
South African endemic
Provincial distribution
Northern Cape
Richtersveld, north-east of Eksteenfontein.
Habitat and Ecology
Major system
Major habitats
Kahams Mountain Desert
Rock crevices on upper slopes.
Severe overstocking of livestock in the Richtersveld is causing ongoing degradation, loss of vegetation cover, and species diversity due to overgrazing and trampling. This species' preference for rocky crevices however may offer it some protection against the effects of grazing. It is also popular in horticulture, and is potentially threatened by collectors removing plants from the wild for the succulent trade.

This species is locally abundant in suitable habitat (Van Jaarsveld 1986).
