Justification | A widespread species that is still common in spite of some habitat loss. Population reduction is however not suspected to exceed 30% in three generations. It is therefore assessed as Least Concern. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Eastern Cape, KwaZulu-Natal, Western Cape |
Range | It is widespread along the southern and eastern coast of South Africa, from the Cape Peninsula to the Pondoland region, southern KwaZulu-Natal. |

Major system | Terrestrial |
Major habitats | Albany Thicket, Fynbos, Indian Ocean Coastal Belt |
Description | Plants grow in coastal and inland dunes as well as sandy coastal flats. |
Threats |
| This species has lost some habitat to coastal development on the Cape Peninsula and along the southern Cape coast, and loss continues. Large areas of its habitat on the southern Cape coast, particularly around the Agulhas Plain are densely infested with alien invasive plants, which are outcompeting native species. |
Population |
A very common species, often dominant in suitable habitat.
|
Population trend | Decreasing |
