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.
