Justification | This species is highly restricted to the Polokwane region. It has an extent of occurrence (EOO) and area of occupancy (AOO) of 12 km². The known subpopulations are severely fragmented, with less than 100 mature individuals recorded. The population continues to decline due to inappropriate urban fire management, mowing, pollution, trampling and agricultural expansion. It is therefore listed as Critically Endangered under criterion B. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Limpopo |
Range | This species is endemic to the Polokwane region in the Limpopo Province, South Africa. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Polokwane Plateau Bushveld |
Description | It grows in sandy and gravelly plains amongst grass and herbaceous plant species. |
Threats |
| Urban development and agricultural expansion in the Polokwane region has resulted in 45% of this species' habitat being irreversibly modified. Remaining remnants of suitable habitat are under significant ongoing pressure from agricultural expansion, trampling (people visiting recreational park), burning, mowing of road verges by the municipality, and pollution (household rubbish or garden refuse). |
Population |
Plants are localised within their habitat, and may have been overlooked as they are small and unnoticeable. It is known from three subpopulations which are isolated and very small in size. The largest subpopulation consists of 52 mature individuals and the smallest has 38 mature individuals.
