This is a Knersvlakte endemic, specifically of the Lutzville part of the Nature Reserve, where it is reasonably well protected except from grazing. This is an inhospitable area with only 50-150 mm of rainfall though Atlantic fogs may occasionally roll in and help the vegetation soak up a little more water. It flowers in the summer months, when the leaves are already dry.
This species is often confused with another Knersvlakte endemic with similar leaves but entirely different flowers. In Marais E. M. (1994), the two taxa are erroneously treated as one species.
