Justification
A long-lived, suffrutescent grassland forb, generation length at least 50 years. Known from two well separated locations that have been extensively transformed by cultivation and forestry plantations and a population reduction of at least 50% is estimated based on habitat loss at these locations since the first collection was made in 1888 (two to three generations). Probably extinct at one location, and searches of areas of suitable habitat between the two sites have failed to locate other subpopulations.

Major habitats
Midlands Mistbelt Grassland, Moist Coast Hinterland Grassland
Description
Mistbelt and Ngongoni Grassland on dolerite, 850-1 600 m.
Threats
The two sites where this species is known from are both in highly transformed areas. Grasslands in the entire area of about 5-10 km surrounding Entumeni, where the type collection was made in 1888, are transformed for the cultivation of crops and forestry plantations. The second site where this species was found is in a fire break surrounded by forestry plantations. It is estimated that at these two sites, at least 50% of the habitat is irreversibly transformed. However, the sites are some distance apart, and the intervening areas are not as highly transformed, but it is not known whether this species occurs in this area or not. On the one hand this is a fairly poorly explored part of KwaZulu-Natal, but on the other, searches in suitable habitat at other areas near Qudeni have failed to locate any further populations (Scott-Shaw 1991, 1999).

Notes
Germishuizen et al. (2006) lists this taxon as a synonym of E. glandulifolia. This is however not based on any publication where this taxon is formally taken into synonymy with E. glandulifolia, and it is therefore assessed as a valid taxon.
