Justification
A extremely rare and poorly known species, currently known from a single subpopulation of 150 mature individuals, but possibly still remaining at two other isolated locations. EOO 757 km², AOO estimated <5 km², this species continues to decline due to ongoing habitat loss and degradation.
Distribution
Endemism
South African endemic
Provincial distribution
Western Cape
Range
Langebaan, Mamre and the Cape Peninsula.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Peninsula Sandstone Fynbos, Hangklip Sand Fynbos, Cape Flats Sand Fynbos, Atlantis Sand Fynbos, Hopefield Sand Fynbos
Description
Sandy flats and lower slopes.
Threats
Threatened by habitat loss to urban expansion on the Cape Flats and Peninsula, and competition from dense infestations of alien invasive plants around Mamre. The only confirmed extant subpopulation occurs within the West Coast National Park, but is situated within a powerline servitude, which is regularly cleared and brushcut.
Population

An extremely rare and seldom recorded species. Previously only known from Mamre and the Cape Peninsula, this species' known range was recently extended as far north as Langebaan, with another isolated subpopulation of about 150 plants recorded in the West Coast National Park in 2012. Prior to this, the species was last recorded in 1997 from near Glencairn on the Cape Peninsula, and from an unspecified locality near Mamre in 1995. In spite of recent and ongoing surveys of lowland fynbos remnants around Mamre for threatened species, this species has not yet been recorded in this area again. A handful of older records date from the 1930s and earlier, and most were collected on the Cape Flats between Rondebosch and Muizenberg, where all subpopulations are now likely to be extinct due to urban expansion, as this species has not been found on well-surveyed remnants such as Kenilworth Racecourse and Rondebosch Common.
