EOO 36 km², AOO<36 km², small, subpopulations at 15-20 locations are declining due to poor recruitment and too frequent fire. It is likely that subpopulations were formerly much larger, as they are confined to pockets of deep sand among granite boulders, with all other surrounding low-lying deep sandy areas ploughed for pasture. Many subpopulations are moribund and consist of senescent adults, sometimes with a few young plants. In the south on Rooiberg and Eselkop by contrast, subpopulations are burned too-frequently and appear to be declining.

Major habitats
Namaqualand Granite Renosterveld, Kamiesberg Granite Fynbos
Largely confined to Kamiesberg Granite Fynbos, among large granite boulders or in the open along the foothills, 1300-1600 m. Mature individuals are killed by fires, and only seeds survive. Seeds are relased after ripening, and dispersed by ants to their underground nests, where they are protected from predation and fire. It is pollinated by insects.
