Family | ORCHIDACEAE |
National Status |
Status and Criteria | Rare |
Assessment Date | 2012/08/29 |
Assessor(s) | L. von Staden |
Justification | A range-restricted (EOO 23 km²), high-altitude habitat specialist that is not threatened. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Hottentots Holland Mountains between Jonkershoek and Sir Lowry's Pass. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Kogelberg Sandstone Fynbos |
Description | High altitude marshes and seeps. |
Threats |
This species' habitat is protected and it has no known threats. It is possibly sensitive to overly-hot fires as two known subpopulations failed to flower after a fire in 2009 (Oliver et al. 2009). |
Population |
Although very a very localized species restricted to a specialized habitat, it is abundant within suitable habitat. The number of subpopulations and the total size of the population is difficult to estimate as this species flowers only after fires.
|
Population trend | Stable |
Notes |
This species flowers only in the first year after fires (Oliver et al. 2011). |
