Description
Damp, peaty rock ledges and cliff faces, 600-1000 m.
Threats
The reasons for the decline of this taxon is not well understood, as plants have disappeared from well-known localities without any apparent reason. It is thought that the plants on Fountain Ledge died due to trampling as a result of extremely high volumes of visitors to the summit of Table Mountain. Some alien invasive pines are present within its habitat, but these are being systematically cleared. Plants are entirely confined to shady fire refuge habitats and may be sensitive to too frequent/intense fires, and appears to be intolerant of strong sunlight.
Population

This extremely rare taxon is endemic to the summit of Table Mountain, where it historically occurred from Fountain Ledge on the Western Table to Constantia Nek. It was occasionally recorded in the 1800s, rarely in the 1900s, and then, by 1995, it was known from about five plants remaining on Fountain Ledge. When these plants disappeared (presumably due to trampling), this taxon was thought to be extinct. It was however rediscovered in 2006 from an area somewhat further south, where after extensive atlasing, it is now known that there are 255 plants surviving in six small clumps over an area of about 1 km².
