Justification
Known from one location (EOO and AOO <10 km²). It has lost most of its habitat to wheat cultivation and road construction in the past. The single remaining subpopulation is on a tiny roadside fragments and is being continually degraded by livestock and invasive alien grasses as well as declining due to low numbers of individuals.
Distribution
Endemism
South African endemic
Provincial distribution
Northern Cape
Range
Nieuwoudtville.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Nieuwoudtville Shale Renosterveld
Description
Renosterveld, sandy clay that may become waterlogged in particularly wet years.
Threats
Less than 10% of this localized species' habitat remain after extensive loss to crop cultivation. Small clumps of plants remain mainly in roadside fragments where they are threatened by overgrazing and competition from alien invasive grasses, which are particularly difficult to eradicate.
Population

One subpopulation is known, it appears to have been one continuous subpopulation stretched out over about 10 km, but has now been much fragmented by habitat transformation.
