Has an extent of occurrence of less than 20,000 km², there are 10 locations but it is also severely fragmented. Although there is no apparent decline at present, there is projected decline due to pressure from succulent collectors. There may also be impacts through clearance of the habitat by charcoal burners. The area of occupancy could be below the threshold for an Endangered listing, but that seems overly precautionary.

|Population:||Very localized but can occur in dense groups.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||A fairly small succulent shrub growing on open granite rock slabs on small hills,with deciduous woodland and grasses on deeper soil. Also recorded from woodland with Brachystegia, Combretum, Sterculia, etc. with outcrops of bare rocks with Xerophyta and Aloe.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
