P.V. Bruyns, D. Raimondo & D.A. Kamundi
A widespread (EOO 27 438 km²), but poorly known central karoo endemic. It is not currently in danger of extinction, but could decline significantly if planned shale gas fracking across its is to go ahead.
South African endemic
Provincial distribution
Northern Cape, Western Cape
Central Karoo, between Prince Albert, Loxton and Merweville.
Habitat and Ecology
Major system
Major habitats
Nama Karoo
Sheltered among the roots of shrubs and in rocky crevices.
There are currently no severe threats to this species. However, its entire known range falls within an area earmarked for shale gas fracking, which could potentially have a severe impact on this species in future. Extraction scenarios are currently too uncertain to derive an estimate of the possible extent of future population reduction.

A widespread, but rarely collected and poorly known species. It is likely to be under-sampled as its distribution range is botanically poorly explored. The population is not suspected to be declining, but may be severely impacted in future if planned shale gas fracking is to go ahead.
