Justification | This is a localized but locally abundant species with an extent of occurrence (EOO) of less than 8 km², and an area of occupancy (AOO) of 8 km². It is not declining despite habitat transformation and degradation. Globally, it is listed as Least Concern, and nationally, as Rare. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | It is endemic to South Africa, and is found in the Langeberg foothills near Grootvadersbos in Western Cape. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Swellendam Silcrete Fynbos |
Description | It occurs in forest margins in loamy clay. |
Threats |
This species has lost 89% of its habitat (calculated using landcover data in GIS). Although this species' habitat is extensively transformed and degraded, it does not appear to have impacted the population. It can still be found growing in the same area where it was first collected in 1775 (P. Goldblatt pers. comm.). |
Population |
This highly localized, but locally abundant species continues to thrive despite extensive degradation, transformation and disturbance of its habitat. Plants can be found growing on roadside banks and cuttings, in pastures and exotic timber plantations, and among invasive thickets of wattle. The population numbers many thousands of plants (P. Goldblatt pers. comm.) and is not declining.
