Justification
Although this species has a wide distribution in the Western Cape Province, it has a small area of occupancy (AOO) of 356 km² and is known from at least 30 subpopulations that are suspected to be declining due to ongoing habitat degradation by the spread of alien invasive plants and inappropriate management of the remaining patches. Therefore, it is listed as Near Threatened under criterion B, as it nearly meets the threshold for Vulnerable.

Major habitats
Swartland Shale Renosterveld, Western Ruens Shale Renosterveld, Swartland Granite Renosterveld, Graafwater Sandstone Fynbos, Bokkeveld Sandstone Fynbos, Cape Winelands Shale Fynbos, Peninsula Granite Fynbos, Boland Granite Fynbos
Description
Plants grow in sandy and stony flats and slopes.
Threats
About 70% of this species' habitat has been irreversibly modified into croplands and urban developments. Plants remain in small patches of renosterveld and fynbos that continue to decline due to agriculture, the spread of invasive alien plants, and inappropriate fire management. Additionally, there is a slight but persistent threat to this species' habitat from pollution in Wellington.
Population

There is no quantitative population data available for this species. It is known from historic collections dating back to 1876-2013 and recent observation records on iNaturalist. Despite the ongoing decline of its habitat, this species still occurs in many remnant patches across a wide range. The population size and trend of this species are unknown; however, it is inferred to be declining due to habitat loss and degradation
