AOO 5 km², three small, severely fragmented subpopulations each consisting of no more than 50 mature individuals are known. The total population is estimated to be less than 250 individuals. Throughout its range it is threatened by coastal development.

Low coastal scrub, close to the coast, in calcareous sands or limestone gravel.
This species is threatened by development (severe past and ongoing threat). Many of the localities in PRECIS are now extinct (P. Goldblatt 2005). According to Manning (2006), one population of approximately 50 plants is on the edge of a development at Blouberg and is likely to go extinct.

It occurs at three sites (one population each) and the size of each population is about 30 plants.

Population trend
Nearly all populations occur within sight of the ocean or only a short distance inland where there are calcareous soils.
