Assessor(s) | L. von Staden |
Justification | Ixia sobolifera subsp. sobolifera is a rare, range-restricted taxon, but also possibly overlooked as it occurs in a botanically relatively poorly explored area. It has an extent of occurrence (EOO) of 2594 km². It is not threatened, and is therefore listed as Least Concern. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape, Western Cape |
Range | This species is endemic to South Africa, and is found in Klein Roggeveld between Sutherland and Matjiesfontein. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Koedoesberge-Moordenaars Karoo, Tanqua Escarpment Shrubland, Central Mountain Shale Renosterveld, Roggeveld Shale Renosterveld |
Description | It grows in well-drained, rocky loam or clay soils in succulent shrubland. |
Threats |
| There are no significant threats to this taxon. |
Population |
Ixia sobolifera subsp. sobolifera has been rarely collected in the past, and field surveys in 2006, a year of exceptionally good rainfall, yielded only five small subpopulations (Goldblatt and Manning 2008). It could possibly still be found elsewhere on the Roggeveld Escarpment and Koedoes Mountains.
