Endemism
South African endemic
Provincial distribution
Western Cape
Range
Porterville to Paarl.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Swartland Alluvium Fynbos
Description
Seasonally moist clay soils in Swartland Alluvium Fynbos.
Threats
This species has already lost most of its habitat to crop cultivation and urban expansion around Paarl, and only small, isolated remnants remain. These fragments continue to be lost to ongoing development, and are otherwise often poorly managed, with mowing, grazing, uncontrolled spread of alien invasive plants and inappropriate fire regimes causing ongoing degradation.
Population

Three small, isolated subpopulations are known to remain, the largest consisting of about 250 mature individuals. Further surveys are needed to confirm whether it still occurs in the Joostenberg area, where it is known from a historical record.


Population trend
Decreasing
