Assessor(s) | R.C. Turner, E.G.H. Oliver, D. Pillay & F. Munro |
Justification | A rare resprouter with a restricted, high-altitude distribution. It has an extent of occurrence (EOO) 60 km² and an area of occupancy (AOO) of 16km². There are only three known subpopulations, two of which are experiencing ongoing declines in habitat quality due to the spread of invasive alien species. This species is therefore listed as Endangered under criterion B. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
