Description | Deep sandy soils on plains and dry riverbeds. |
Threats |
| On the Namibian and South African coast, as well as at places along the lower Gariep Valley, this species is threatened by ongoing habitat loss and degradation due to mining. It is also threatened across its range in South Africa by severe overgrazing. |
