Justification
EOO between 445 and 11 158 km² and suspected to occur at fewer than 10 locations. It has lost habitat to crop cultivation in the past. It is currently threatened by ongoing degradation and habitat loss due to overgrazing and urban development.

Description
Undulating grasslands in damp areas.
Threats
Crop cultivation is a past threat that lead to extensive loss of habitat. At present urban development on the banks of the Vaal Dam are causing ongoing loss of habitat. Invasive alien plants threaten a number of subpopulations. Habitat degradation by livestock has meant that several habitats in western Mpumalanga are currently under threat. This threat is however reversible as one subpopulation in Mpumalanga has had livestock removed and has recovered well.
Population

Sizes of subpopulations vary greatly depending on land management. The subpopulation in Mpumalanga that has had livestock removed is very health consisting of millions of plants. During a survey in 2002 no plants were found around the Vaal Dam, although there are records of its occurrence there between 1977 and 1988.
