Scientific Name | Cyanella alba L.f. subsp. alba |
Higher Classification | Monocotyledons |
Family | TECOPHILAEACEAE |
Common Names | Handjie (a), Lady's Hand (e), Toetels (a), Toe-toe (a), Toe-toe-uintjie (a), Tu-tu-uintjie (a) |
National Status |
Status and Criteria | Vulnerable B1ab(iii,v)+2ab(iii,v) |
Assessment Date | 2015/06/01 |
Assessor(s) | L. von Staden |
Justification | A range-restricted (EOO 408 km²), but locally fairly common subspecies. In spite of extensive habitat loss, it is estimated to still remain at between eight and 10 locations, but continues to decline due to ongoing habitat loss and degradation. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape, Western Cape |
Range | Bokkeveld Escarpment around Nieuwoudtville to Botterkloof. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Hantam Karoo, Nieuwoudtville Shale Renosterveld, Vanrhynsdorp Shale Renosterveld, Bokkeveld Sandstone Fynbos |
Description | Seasonally damp, shallow sandy or clay soils on flats. |
Threats |
| This subspecies has already lost more than 30% of its habitat to agricultural expansion across the Bokkeveld Escarpment. Although ploughing of especially clay soils has largely ceased, there is still ongoing, sporadic expansion of crop fields. The population has been fragmented, and in some places, remaining subpopulations are threatened by overgrazing, due to overstocking of remnants of natural vegetation. Alien invasive plants have been observed in subpopulations south of Nieuwoudtville, and if left unmanaged, are likely to cause habitat degradation and competition to this subspecies in future. |
Population |
This subspecies is locally abundant across the Bokkeveld Escarpment.

Population trend | Decreasing |
