Scientific Name | Manulea minor Diels |
Higher Classification | Dicotyledons |
Family | SCROPHULARIACEAE |
National Status |
Status and Criteria | Critically Endangered (Possibly Extinct) |
Assessment Date | 2018/05/10 |
Assessor(s) | L. von Staden |
Justification | A highly range-restricted species (EOO 7 km²) that was last recorded in 1944. Most of the natural vegetation within its known range has been irreversibly modified, and it is not known whether the population has survived. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Hex River Valley. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Breede Alluvium Fynbos |
Description | Sandy flats and lower slopes. |
Threats |
The specific habitat requirements of this species is not well known, but altitude notes on specimens suggest that it occurs on lower slopes and flats. These areas within the Hex River Valley has been extensively converted to vineyards, as well as lost to urban expansion around De Doorns. It is an annual species that is possibly resilient to disturbance, but the 70+ years since it was last recorded is a cause for concern. |
Population |
This species was last recorded in 1944 near Orchard siding in the Hex River Valley. Current status and trend of the population is not known, and searches are urgently needed to relocate this species in the wild.
