État de la populationTexte officiel évaluation IUCNExpert
This species had already lost 58% of its habitat by 1996, and recent surveys indicate that the subpopulation at the type locality is extinct. The habitat destruction is irreversible and ongoing, as there is renewed interest in mining in Sekhukhuneland. A past population reduction of at least 50% over 90 years (three generations) is inferred from the extent of habitat loss. It is, however, not declining at present, although there is a strong chance that the habitat will decline further in future.

Description complète des menacesTexte détaillé évaluation IUCNExpert
Sekhukhune Plains Bushveld is one of the most threatened vegetation types of the Sekhukhune Centre of Endemism. The area around Leolo Mountain where this species occurs was already 58% transformed in 1996, mainly by mining, human settlements, cultivation and land degradation due to overgrazing of communal rangelands. The subpopulation at the type locality, Driekop farm, Leolo Mountain, may be extinct, as attempts to relocate individuals have failed, and the site is completely degraded by chrome mining. Subpopulations at two other known sites at Potlake Nature Reserve are not currently declining, but there is a potential threat of mining at the site outside the reserve. According to Obermeyer and Immelman (1992), this species is harvested for medicinal use. They do not indicate, however, what part of the plant is utilized.
