Justification
EOO 89 754 km², AOO <100 km². Known from 12 locations but likely to occur at many more. Its sodic pan habitat is relatively common in the Free State, North West and in the Northern parts of the Northern Cape. Despite much of its range being utilised for crop cultivation this taxon occurs in a micro habitat that is not ploughed and is thus not likely to be declining.

Description
Grows in areas of high 'sodic' soils especially at the edges of salt pans and in saline vleis.
Threats
No severe threats. The waterlogged and often saline habitat of this species is not suitable for crop cultivation. There are potential threats of overgrazing, salt mining, and erosion, but these do not currently have a severe impact on this species (Hahn 2013).
Population

This species is locally abundant in suitable habitat, and subpopulations are large. The population is not suspected to be declining.
