A rare and poorly known species (EOO 2911 km²), that is potentially threatened by habitat loss and degradation in the southern part of its range, but not yet in danger of extinction.
South African endemic
Provincial distribution
Northern Cape
Namaqualand, Komaggas to Garies.
Habitat and Ecology
Major system
Major habitats
Succulent Karoo
Loamy soils on coastal flats and gently sloping hills.
This species is likely to be threatened by illegal collection of mature individuals from the wild (N.A. Helme, R.H. Archer pers. comm.), but no direct observations of loss of subpopulations have yet been reported. Around Kotzesrus it is also threatened by road upgrades and pipeline construction. Threats elsewhere in its range are not known, and most of its habitat remains intact.

Field observations around Kotzesrus indicate that this species occurs in very low numbers, and subpopulations number fewer than 10 mature individuals (N.A. Helme pers. obs.). Bruyns reports this species to be common further north, around Wallekraal and Riethuis. The population possibly numbers fewer than 1000 mature individuals (N.A. Helme pers. comm.), but more field surveys are needed to confirm this.
