Status and Criteria | Critically Endangered C2a(ii) |

Justification | This species was formerly thought to be extinct after more than 95% of its habitat was lost to urban expansion, vineyards and timber plantations, however, it was rediscovered at a site earmarked for development in 2001, and in 2012, a single plant was found on another small fragment about five kilometres away. The population is estimated to number fewer than 250 mature individuals, and continues to decline due to ongoing habitat loss and degradation. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Wemmershoek to Stellenbosch. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Swartland Alluvium Fynbos |
Description | Sandy flats in Swartland Alluvium Fynbos. |
Threats |
| Less than 10% of this species' habitat remains after loss to urban expansion, vineyards, and timber plantations. Two remaining locations, both small, degraded fragments, are threatened by ongoing habitat loss to housing developments, quarrying, unmanaged alien invasive plants and further agricultural expansion. |
Population |
Historical records indicate that this lowland Alluvium Fynbos endemic formerly occurred along the Dwars and Berg River valleys between Banhoek, Wemmershoek and Franschhoek, but currently plants survive on two small, isolated and severely degraded fragments. On one fragment, earmarked for development, plants were abundant after a fire in 2001, but subsequently very few plants could be found (C. Klak pers. comm.). In 2012, one plant was found on a second fragment which burnt about four years ago.
