Description
Sheer rock faces derived from quartzitic sandstone of the Witteberg Group, usually in light shade.
Threats
No known threats. Although this species has been reported to be becoming rarer, the population was observed to be healthy and abundant in 2007 (E. van Jaarsveld pers. obs.). Plants are cryptic and easily overlooked, and the habitat is inaccessible. The area is used predominantly for game farming and ecotourism, and there are no direct threats to the habitat.
Population

Plants grow singly or in small clumps, often wedged into vertical rock crevices, and is not suspected to be declining.
