Assessor(s) | J.C. Manning, D. Raimondo, R.C. Turner & L. von Staden |
Justification | When the population was surveyed in the spring of 2006, only 100 plants were seen. Its seasonally wet, lowland habitat has been mostly lost to ploughing for vineyards and cereal crops in the past. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Tulbagh. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Swartland Alluvium Fynbos |
Description | Seasonally wet, lowland shales in alluvium fynbos. |
Threats |
| This species has lost most of its habitat to crop cultivation in the past. The only known remaining subpopulation occurs in a private nature reserve, and is not threatened at present. |
Population |
This species is known from only a few, very old historical records from the Tulbagh Valley, where it is now locally extinct due to habitat loss to agricultural expansion. It is currently known from a single, small subpopulation of about 100 mature individuals occurring in Swartland Alluvium Fynbos in a private nature reserve at the foot of the Elandsberg Mountains south-west of Tulbagh.
