Justification
This taxon has a restricted distribution range, with an extent of occurrence (EOO) of 4285 km². It is known from 10-15 locations, and is declining due to ongoing habitat loss to crop cultivation.
Distribution
Endemism
South African endemic
Provincial distribution
Northern Cape, Western Cape
Range
This taxon occurs from the Bokkeveld Escarpment around Nieuwoudtville in the Northern Cape southwards to the Cederberg Mountains in the Western Cape.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Cederberg Sandstone Fynbos, Bokkeveld Sandstone Fynbos, Swartruggens Quartzite Fynbos
Description
It occurs on sandy and gravelly flats and slopes in fynbos. Mature fruits split open and the seeds are dispersed by wind over a large area. Pollinators are not known, but it is likely to be pollinated by bees due its sweetly-scented flowers.
Threats
On the Bokkeveld Escarpment and in the Gifberg there is ongoing habitat loss to rooibos tea cultivation. Subpopulations in the Cederberg are not threatened.
Population

Plants occur as scattered individuals or in small groups (Duncan 2012). A continuing decline is inferred from ongoing habitat loss.
