Higher Classification | Monocotyledons |
Family | IRIDACEAE |
National Status |
Status and Criteria | Vulnerable D2 |
Assessment Date | 2014/04/21 |
Assessor(s) | L. von Staden |
Justification | A localized habitat specialist (EOO <20 km²) that is potentially threatened by habitat loss to agriculture. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Karoopoort between Ceres and Touwsrivier. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Matjiesfontein Shale Renosterveld, Tanqua Wash Riviere |
Description | Dry washes of sandy alluvium overlaying shale. |
Threats |
| Alluvial soils within this species' known range are cultivated in places, but agricultural expansion is slow and sporadic, as the area is dry and only marginally suitable to crop cultivation. Only one location can be determined with precision, and at this site there is no immediate threat to this species. It is however potentially threatened by habitat loss to agricultural expansion. |
Population |
This rare and localized species is known from only two collections along a 10 km stretch of road on the arid western fringe of the fynbos biome. More surveys are needed to determine the size and extent of the population.
