Justification
A population reduction of nearly 30% is estimated based on a 27% reduction in range size due to habitat loss to forestry plantations, agriculture and overgrazing in the past 100 years (generation length >100 years). Also threatened by too frequent fire.
Distribution
Endemism
Not endemic to South Africa
Provincial distribution
KwaZulu-Natal, Mpumalanga
Range
Barberton and Carolina, Swaziland escarpment, Mapumulo, Ndwedwe and New Hanover.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Grassland
Description
Shallow sandstone-derived soils in Ngongoni and Mistbelt Grassland from 900-1100 m. Associated with serpentine. A resprouter that survives regular fires well. Prefers deeper soils than P. parvula.
Threats
Afforestation (Pine), agriculture (pasture), too-frequent fires, overgrazing (cattle), and naturally fragmented subpopulations threaten the survival of this species.
Population

Locally common, but usually confined to localized subpopulations.


Population trend
Decreasing
Notes
The KwaZulu-Natal subpopulations have broader leaves than Swaziland-Mpumalanga subpopulations. Despite there being no subpopulations between the two 'there is a gradation' between the two subpopulations and subspecific status has not been recognized (Rourke 1972). Subspecies status should be recognized and conservation action taken accordingly.
