Assessor(s) | A.G. Rebelo, H. Mtshali & L. von Staden |
Justification | A population reduction of >50% is estimated based on a 80% reduction in range size (EOO) and 51% habitat loss, mainly to crop cultivation, in the past 100 years (generation length 100 years). 37% of subpopulations known through herbarium records are now locally extinct. EOO 2222 km², AOO 45 km², five small, severely fragmented remaining subpopulations continue to decline due to ongoing habitat loss and fragmentation, skewed sex ratios in small fragments, recruitment failure, herbicide drift from adjacent crop fields and overgrazing. |

Description | A renosterveld and renosterveld-ecotone species usually associated with silcrete and pallid zone clays. It is a long-lived species, and survives fires by resprouting from underground boles or rootstocks. Wind-dispersed seeds are released after ripening, and is stored in surface leaf-litter. It is dioecious, with insect-pollinated male and female flowers occuring on separate plants. |
