Justification | This is a widespread and common species, with an extent of occurrence (EOO) of 20 470 km², and an area of occupancy (AOO) of 212 km². Even though it has lost some of its habitat, it is still very common. It is not affected by disturbance, and is therefore not in danger of extinction. It is listed as Least Concern. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | It is endemic to South Africa, and is widespread in the southwestern Western Cape. It is found from Hopefield and Saldanha Bay in the west to Bredasdorp in the east. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Fynbos |
Description | It occurs in sandy, seasonally waterlogged lower slopes and flats, occasionally wet clay soils. |
Threats |
| This species is threatened by ongoing habitat loss to urban expansion on the Cape Flats and coastal areas between Betty's Bay and Cape Agulhas. It also under threat from competition by unmanaged alien invasive plants across its range. However, it is very common and is not in danger of extinction. |
Population |
In spite of extensive habitat loss and degradation, it is still very common. The population has a stable trend. Recent field observations indicate that it is extant at more than 30 subpopulations. It is tolerant of disturbance, and even in severely disturbed sites it can be found flowering in masses (Goldblatt and Manning 2013). There are hundreds of recent observations of this species made on iNaturalist.
