Description
Alkaline, seasonally inundated granitic clay pans.
Threats
Much of the area surrounding the seasonal pans where this species occurs has been ploughed for crops. Although the pans are not cultivated, they are vulnerable to disruption of water flow dynamics due to modification of the surrounding area. The largest subpopulation occurs on a pan that is currently in good condition and not facing any immediate threat, but a second, smaller subpopulation is potentially threatened by habitat degradation due to grazing and trampling by livestock.
Population

This species is locally abundant, but very localized, with several thousand plants in the largest subpopulation, occupying a single pan of 1.5 ha. A second subpopulation of <30 plants occur in a similar, but more degraded pan about 5 km away.
