Description
Crevices in weathered quartzitic sandstone.
Threats
Sandstone fynbos around known subpopulations of this taxon are being rapidly ploughed up for rooibos tea cultivation - crop fields are often within tens of meters of subpopulations. This taxon however occurs wedged in crevices in sandstone outcrops that are unsuitable to cultivation, and ploughing has had little or no impact on the population. The indirect impacts of agricultural activities such as herbicide and fertilizer drift are not known.
Population

This taxon is locally abundant, with the population estimated to be 5000-10 000 mature individuals. It is not declining.
