Justification
This species is widespread in the Eastern Cape, with an extent of occurrence (EOO) of 29 389 km². While some parts of its habitat are declining due to housing developments and alien plant invasion, it remains extant at more than 30 subpopulations. It is therefore listed as Least Concern.
Distribution
Endemism
South African endemic
Provincial distribution
Eastern Cape
Range
This species has a wide distribution in the Eastern Cape, where it occurs from Zuurberg eastwards to Baziya in the southern Drakensberg and Port St Johns.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Amathole Montane Grassland, Kasouga Dune Thicket, Albany Valley Thicket
Description
It occurs in coastal and inland rocky grassland.
Threats
This species has lost habitat to urban development and timber plantations on slopes of Amathole, Hogsback and Stutterheim mountains in the past. Timber plantations are no longer expanding, and thus habitat loss has ceased, but plantations are a major source of invasive pine seedlings that are spreading into surrounding native vegetation.
Population

It is known mostly from old herbarium collections records. A continuing population decline is inferred from ongoing habitat loss to urban development and alien plant invasion. Monitoring of the population is required.
