Scientific Name | Manulea praeterita Hilliard |
Higher Classification | Dicotyledons |
Family | SCROPHULARIACEAE |
National Status |
Status and Criteria | Least Concern |
Assessment Date | 2016/10/03 |
Assessor(s) | L. von Staden |
Justification | A range-restricted (EOO 2318 km²) and relatively poorly known species that is suspected to be overlooked, rather than rare or threatened. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Northern Cape, Western Cape |
Range | Bokkeveld Escarpment, northern Cederberg and Olifants River Valley. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Fynbos, Succulent Karoo |
Description | Sandy flats and slopes. |
Threats |
| There is ongoing loss of sandstone fynbos in areas with deep sandy soils within this species' known range, as a result of rapid, ongoing expansion of rooibos tea cultivation. This species' annual habit suggests that it is probably adapted to disturbance, and unlikely to be severely impacted by agricultural expansion. It is possibly threatened by overgrazing on the sandy plains south of Vanrhynsdorp, but this is likely to affect only a small proportion of the population. |
Population |
Manulea praeterita is known from only a few collections, but is likely overlooked, and more common than records suggest. As an annual species, it is likely to be resilient to disturbance, and the population is not suspected to be declining.
