Justification
This species has an extent of occurrence (EOO) of 19 982 km², and an area of occupancy (AOO) of 260 km². At least 35 locations remain of this formerly widespread and common species. It is now largely confined to small fragments due to over 68% habitat loss to crop cultivation. This decline in habitat continues. It is therefore listed as Near Threatened, almost meeting criteria B to be listed as Vulnerable.
Distribution
Endemism
South African endemic
Provincial distribution
Western Cape
Range
It is endemic to South Africa, and is common in the southwestern Cape lowlands. It is found from Wolseley to Heidelberg, Hermanus and the Agulhas Plain in Western Cape.

Description
It occurs in lowland and alluvial shale and silcrete renosterveld and fynbos, occasionally in limestone fynbos.
Threats
This species' habitat is already 68% transformed (calculated using landcover data in GIS), predominantly for crop cultivation. It has also lost habitat to urban expansion, and on the Agulhas Plain remaining subpopulations are threatened by competition from alien invasive plants. Most subpopulations occur on small fragments among crop fields, where they are subjected to heavy overgrazing as these small fragments are frequently overstocked.
Population

It is a widespread, and formerly abundant species that has declined extensively due to habitat loss and fragmentation. Although still fairly common, the decline continues, and subpopulations are increasingly isolated in small fragments of natural vegetation. Between 50-100 plants were observed in a commonage in Napier in 2016 and a subpopulation occurring on the road to Karwyderskraal also had between 50-100 plants in 2015. In 2022, 50 plants and less than 10 plants were observed in two subpopulations near Napier, while less than 10 plants were observed in the Overberg district municipality in the same year.
