Justification
This species has a limited distribution range and has an extent of occurrence (EOO) of 5497 km² and an area of occupancy (AOO) of 220 km². The subpopulations are small and severely fragmented, with a continuing decline due to mining and harvesting for horticultural purposes. It therefore qualifies as Endangered under criterion B.
Distribution
Endemism
South African endemic
Provincial distribution
Limpopo, Mpumalanga
Range
This species has a distribution ranging from Roossenekal to Dullstroom in Limpopo and Mpumalanga province, South Africa.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Sekhukhune Mountain Bushveld, Steenkampsberg Montane Grassland, Sekhukhune Montane Grassland
Description
It occurs among dolerite boulders in open woodland and in rocky grasslands.
Threats
This species is threatened by illegal collection to supply the horticultural markets. Habitat destruction as a result of norite mining also poses a threat to the persistence of this species in the wild. According to Craib (2003) this species is also threatened by predation by porcupines.
Population

No population data are available for this species, but it is suspected to be declining due to illegal collection for the horticultural trade. Subpopulations are always small—fewer than 50 mature individuals—and they are typically isolated from one another.


Population trend
Decreasing
Conservation
It is potentially conserved in a biosphere reserve.
