Justification | Around 45% of this species' sandy habitat has been lost over the past 100 years to agriculture, urban expansion and severe alien plant invasion. It is a long-lived resprouter (generation length estimated to be 40 years). Furthermore it is probably extinct at over 50% of the 142 sites represented by herbarium records, and most have been lost in the past 120 years. Sampling may have been biased towards the lowland flats and it is likely that lower mountain slopes are not adequately represented in herbaria. Thus the overall loss to the population over the past three generations is suspected to be between 30-50%. |

Description | Plants grow in sandy flats and sandy areas on lower mountain slopes. |
Threats |
| Most of the sandy flats subpopulations have disappeared to alien invasive species, urban development and crop cultivation. 45% of this species habitat has been lost over the past 100 years. It is also threatened by agriculture, especially vines (N.A. Helme, 2006). |
Population |
Population trend | Decreasing |
Conservation |
| It is conserved in Cape of Good Hope Nature Reserve and Kammanassie. |
