Description
Cracks and fissures of granite domes, particularly in areas sheltered under rock lips, but also at the edges of shallow grit pans.
Threats
This taxon is closely related to Conophytum buysianum, which is known to be targeted for illegal succulent collecting. Although locally abundant, is extremely localized in its distribution range, and removal of plants from the wild is likely to put it at risk of extinction. Habitat loss and degradation due to mining is also a potential threat - prospecting activities have been observed near subpopulations of this taxon (Young et al. 2011).
Population

This taxon has a restricted range, but is locally abundant, with subpopulations all numbering several thousand individuals.


Population trend
Stable
