Justification
EOO 300 km², AOO <300 km², known from a collection on Ladismith commonage which is declining and currently has fewer than 50 plants, and from a second collection from the foothills of Anysberg in an area that is not threatened. It is likely that quite a few more subpopulations exist as this is a small, cryptic, autumn-flowering species. We suspect that there are between five and 10 locations. Habitat is being lost to crop cultivation, and urban and industrial development.
Distribution
Endemism
South African endemic
Provincial distribution
Western Cape
Range
Ladismith.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Montagu Shale Renosterveld, Western Little Karoo
Description
Low rocky hills on shale.
Threats
Urban expansion is a threat at the Ladismith location (J. Manning 2005). Other threats occur near the factory, where the species is threatened by development and urban expansion. Western populations towards Anysberg are likely to be safe.
