Assessor(s)
G.D. Duncan & L. von Staden
Justification
Known from a single subpopulation, where it was last seen in 1962. It has not been relocated despite several searches, and may possibly be extinct in the wild.
Distribution
Endemism
South African endemic
Provincial distribution
Northern Cape
Range
Nieuwoudtville.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Nieuwoudtville-Roggeveld Dolerite Renosterveld
Description
Karoo shrubland on red clay soils in dolerite rock cracks.
Threats
It is not certain what caused the disappearance of the only known population, but the area has been grazed by livestock for many years, and is partially invaded by alien invasive grasses.
Population

This species was collected once, in 1962, at a well-known locality on the Bokkeveld Escarpment near Nieuwoudtville. Despite many subsequent botanical surveys of the area, as well as numerous targeted searches, it has never been seen again. Similar habitat elsewhere on the Bokkeveld Escarpment is also botanically well-explored. The population is either extinct, or requires very specific conditions to flower. Plants remain in cultivation at Kirstenbosch Botanical Garden (Duncan 2012).
