Justification
A relatively widespread (EOO 18 802 km²), but very poorly known species last recorded in 1935. The reason for the lack of records is not known, it may be rare and overlooked, or possibly threatened by overgrazing. Field surveys are needed to relocate it in the wild. Based on currently available data, its risk of extinction cannot be assessed.
Distribution
Endemism
South African endemic
Provincial distribution
Eastern Cape, Northern Cape
Range
Eastern Karoo, from Britstown to Burgersdorp, and southwards to Cradock.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Eastern Upper Karoo
Description
Karroid shrubland, possibly restricted to koppies.
Threats
Unknown. The fact that this species was last recorded in 1935 is concerning. J.P.H. Acocks surveyed 172 plots within its known distribution range in the 1950s and 60s, and did not record it once. It may be affected by overgrazing, but field surveys are needed to confirm this.
Population

A very poorly known species, known from only five collections and last recorded in 1935. It is suspected to be rare, as it has not been recorded in numerous vegetation surveys within its known range. The population trend is unknown.
