Terrestrial
Major habitats
Amathole Mistbelt Grassland
Description
Steep rocky dolerite slopes and ridges in mistbelt grassland.
Threats
Threatened by habitat loss to timber plantations, encroaching alien invasive plants, and overgrazing. It is not known why the subpopulation at the type locality disappeared - possibly as a result of grazing. There are at present no threats to the subpopulation discovered in 2015, but nearby grasslands have some escaped pines in it, which may spread if left unmanaged. The site is not grazed (N.A. Helme pers. comm. 2015).
Population

This species was previously known from a single collection, dating from 1926. The locality, Gaika's Kop, is fairly accurately documented, but several searches in this area failed to relocate the subpopulation (A. de Castro pers. comm.). In 2015, a second subpopulation was discovered in similar habitat about 10 km away. This subpopulation is large, consisting of over 1000 mature individuals, and is not under any threat (N.A. Helme pers. comm.). It is likely that other subpopulations exist in similar habitat between Hogsback and Cathcart, and these areas need to be surveyed.
