Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape, Western Cape |
Range | Namaqualand, Garies to Kliprand, Loeriesfontein and Brand-se-baai. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Namaqualand Strandveld, Namaqualand Heuweltjie Strandveld, Namaqualand Heuweltjieveld, Namaqualand Blomveld, Knersvlakte Shale Vygieveld, Namaqualand Sand Fynbos |
Description | Deep, red sandy soils on flats, granitic sand at the base of granite outcrops, and clay soils on alluvial plains. |
Threats |
Subpopulations near the coast are threatened by expanding open cast sand mining. At a few known locations, plants are subjected to heavy grazing, but does not appear to be negatively impacted by grazing. |
Population |
At some locations further inland, very few plants were recorded (G. Duncan, pers. obs.), however in deep sands near the coast, subpopulations number many thousands of plants (N.A. Helme, pers. obs.).
