South African endemic
Provincial distribution
Northern Cape, Western Cape

Deep sandy flats.
Threats
Habitat loss to potato cultivation is causing ongoing decline in subpopulations in the Sandveld around Hopefield, and alien invasive plants are threatening subpopulations throughout the range. Coastal development between Blouberg Strand and Yzerfontein is also likely to be causing population decline.
