Justification
This Cape Flats endemic has lost all of its habitat to urban expansion of the City of Cape Town. It persists in one subpopulation, where there are fewer than 50 plants growing in a completely transformed habitat in Observatory.
Distribution
Endemism
South African endemic
Provincial distribution
Western Cape
Range
Formerly recorded from the Cape Peninsula between Cape Town and Rondebosch. A single subpopulation remains at Observatory.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Fynbos
Description
Clay slopes and flats.
Threats
Urban expansion of the city of City of Cape Town resulted in the severe decline of this species, and a single, small population persists in a severely degraded area in the middle of a Cape Town suburb. The small fragment where this species grows is densely invaded by exotic and alien invasive species, particularly grasses, to such an extent that it is no longer considered natural. Flowering is very erratic, possibly as a result of unfavourable habitat conditions, and as a result seed set is very low. Too few individuals remain to be considered a viable population, and this species is on the brink of extinction in the wild.
