Scientific Name | Nemesia elata K.E.Steiner |
Higher Classification | Dicotyledons |
Family | SCROPHULARIACEAE |
National Status |
Status and Criteria | Vulnerable B1ab(iii,v)+2ab(iii,v) |
Assessment Date | 2011/06/19 |
Assessor(s) | J.H. Vlok, D. Raimondo & L. von Staden |
Justification | This species was known since its discovery from only a single location on the top of Montagu Pass. It was only recently described (2010) and further surveys of herbarium material and field surveys of the Outeniqua and Langeberg mountains confirmed at least six locations within an EOO of 351 km². This extremely rare habitat specialist can be locally common after fires, but is threatened by inappropriate fire management, alien invasive plants, as well as road and other infrastructure construction. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Langeberg and Outeniqua mountains between Swellendam and George. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | South Outeniqua Sandstone Fynbos, South Langeberg Sandstone Fynbos |
Description | Moist, steep slopes in gorges and ravines. |
Threats |
| Threatened by infrastructural development (roads and railways), infestation by aliens and inappropriate fire management, this species only flowers after fire and requires intense burns, recently fires have been managed and intense fires are now rare. (J. Vlok 2007). |
Population |
The species is very common after fire (Steiner 2010), but dies back in mature vegetation (J. Vlok pers. comm.). It appears to be rare, and requiring very specific fire conditions to flower. It may also be overlooked due to the combination of the specialized, and often inaccessible habitat and sporadic flowering.
