Justification
EOO 11 500 km², known from more than 12 subpopulations, many of which are conserved within nature reserves. This species is fairly common and not in danger of extinction.
Distribution
Endemism
South African endemic
Provincial distribution
Mpumalanga
Range
Mpumalanga Highveld, between Dullstroom, Pilgrim's Rest and Lydenburg.
Habitat and Ecology
Major system
Terrestrial
Description
Grassy mountain slopes, in deeper soils in wet sites or around the edges of damp depressions. 2100-2400m.
Threats
This species has lost habitat to timber plantations in the past, but this is not an ongoing threat, with plantations not significantly expanding. It is possibly threatened in places by competition from unmanaged alien invasive plants.
Population

Plants occur as isolated individuals and never as dense colonies, it therefore appears rare, but it has been recorded from many localities (Goldblatt and Manning 1998).
