Justification | Known from four locations in an area of 750 km². This species is a long-lived geophyte (generation length 20 years), which has lost a minimum of 30% of its habitat in the past 60 years to crop cultivation. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape, Western Cape |
Range | This species has a limited distribution in Namaqualand, from Vanrhynsdorp to Calvinia. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Tanqua Karoo, Vanrhynsdorp Gannabosveld |
Description | Succulent karoo, in either wind-blown sand or stony soils thought to be rich in lime, overlying dolomite rocks. |
Threats |
| At least 30% of this species' habitat has been lost to crop cultivation in the past three generations. Only four subpopulations remain, one of which was nearly lost in 2004 to expanding crop fields, fortunately as a result of the intervention of the local conservation authority the land was set aside by the landowner for conservation. The remaining three subpopulations are threatened by invasive alien plant encroachment. |
