Higher Classification | Dicotyledons |
Family | AIZOACEAE |
Synonyms | Astridia dinteri (L.Bolus) L.Bolus var. lutata L.Bolus ex H.Jacobsen, Astridia velutina Dinter & Schwantes var. lutata L.Bolus |
National Status |
Status and Criteria | Data Deficient - Insufficient Information |
Assessment Date | 2015/06/12 |
Assessor(s) | D. Raimondo |
Justification | An apparently rare and localized, but poorly known species last observed in 1926. It is threatened by ongoing habitat loss and degradation, but until it can be relocated, an estimate of its risk of extinction cannot be made. |
Distribution |
Endemism | Not endemic to South Africa |
Provincial distribution | Northern Cape |
Range | Orange River Valley between Arris Drift and Sendelingsdrif. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Desert |
Description | Uncertain, possibly shale or mixed rubble outcrops. |
Threats |
| Threatened by ongoing habitat loss to mining, as well as degradation due to overgrazing and trampling. |
Population |
This species is only known from the type collection, made in 1926. The locality description indicates a 35 km stretch of the Orange River Valley that is now mostly severely degraded due to mining. Relocating this species over such a large area is difficult, and access to mining sites is often restricted. It also makes the estimation of its range size very uncertain, but it is likely to be localized as this area is rich in endemics, as well as likely to be declining due to ongoing habitat loss and degradation.
