A highly range-restricted species (EOO 13 km²), remaining at three to five locations after extensive habitat loss to urban expansion and crop cultivation, and declining due to ongoing habitat loss and degradation.
South African endemic
Provincial distribution
Western Cape
Northern Vredenburg Peninsula between Vredenburg and St. Helena Bay.
Habitat and Ecology
Major system
Major habitats
Saldanha Granite Strandveld, Saldanha Limestone Strandveld
Seasonally moist depressions and rock crevices around exposed rock sheets in Saldanha Granite Strandveld.
Agricultural expansion has caused extensive habitat loss on the Vredenburg Peninsula, and only a few fragments of Saldanha Granite Strandveld remains intact. The subpopulation at the type locality near Vredenburg is now locally extinct as a result of urban expansion. The largest remaining subpopulation near St. Helena Bay is threatened by habitat loss to coastal development. A second subpopulation on a privately owned farm is threatened by habitat degradation due to overgrazing. Recently there was an application to establish wind turbines on this piece of land, and the conditions attached to the environmental authorisation was that livestock should be removed from the piece of land. The population is however still likely to be impacted by infrastructure development at the site.

There are only two known existing subpopulations of this species. A third, known from historical records, has not been relocated for 10 years despite searches in the area, and it is presumed extinct. Both existing subpopulations occur on some of the last remaining remnants of Saldanha Granite Standveld around St. Helena Bay. The largest subpopulation consists of more than 1000 mature individuals scattered across several properties earmarked for development. The second subpopulation is much smaller, consisting of fewer than 100 mature individuals.
