Justification
A range-restricted species (EOO <1 km², AOO <1km²) with a population size of less than 300 individuals. The population is at present stable, but is potentially threatened by succulent collecting and habitat loss to mining, which would rapidly lead to an increase in risk of extinction.
Distribution
Endemism
South African endemic
Provincial distribution
Northern Cape
Range
Namaqualand, near Platbakkies.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Platbakkies Succulent Shrubland
Description
Shaded west-facing cliff faces, occurring on dark rocks of unknown geology, possibly containing iron.
Threats
This rare species is potentially threatened by illegal succulent collection. The population is extremely small and any removal of plants from the wild is likely to increase its risk of extinction. There is also increasing mining pressure across Namaqualand, and the unusual substrate on which this species occurs may be targeted for mining.
Population

This species is extremely rare, and is currently known from a single, small population of about 300 mature individuals. It occupies a unique geological formation, and is likely to be a localized habitat specialist. Surveys by several botanists of immediate area have so far failed to yield any additional subpopulations.
