Justification
A highly range-restricted species (EOO 36 km²) known from one location. Part of the population was destroyed as a result of a road being widened. It was thought that the entire population had been lost, but some individuals were discovered away from the road. Unfortunately this subpopulation is in the midst of a recently established, illegal informal settlement. The population is thus expected to decline further due to ongoing development and degradation of the site. There are fewer than 200 individuals of this species remaining.

Major habitats
Midlands Mistbelt Grassland, Southern Mistbelt Forest
Description
Mistbelt grassland, coarse herbage in deeper soils on steep, shady banks in forest-grassland ecotones, 1 200-1 300 m.
Threats
Mistbelt grasslands have been extensively transformed in the past for forestry plantations and agriculture. The deep soils on cool, moist south-facing slopes where this species grows are particularly favourable to agriculture and forestry (C.R. Scott-Shaw pers. comm.) and only about 1% remains intact (Scott-Shaw 1999). This species has only been known from the type locality along the road south of Ixopo, and part of the population was destroyed when the road was widened. It was thought that the only known population had been lost, but later, Rob Scott-Shaw discovered some remaining individuals further away from the road amidst a recently established informal settlement. The population is expected to decline further due to ongoing development and degradation of the site.
