Justification: This species has a restricted distribution, with an extent of occurrence (EOO) of 314.493 km², and an area of occupancy (AOO) of 36 km². It is known from between seven and ten locations. More than half the range is subject to ongoing heavy grazing by livestock resulting in habitat degradation. Based on this, it has been assessed as Vulnerable, under Criterion B.
History:	-

Geographic Range
Range Description:	This species has been found in the Eswatini highveld, in sourveld grassland areas.
Countries:	Native: Eswatini;

Population
Population:	There is currently no detailed population information for this species, no surveys have been conducted. For the purposes of this assessment, it has been assumed that the plant still occurs at the locations recorded on older collections. The population trend is unknown.
Population Trend:	Unknown

Habitat and Ecology
Habitat and Ecology:	This plant is known from grassland areas in the Eswatini highveld. The records are from the grassland biome, vegetation type KaNgwane Montane Grassland (Gm16) (Mucina et. al. 2018).
List of Habitats:	4 Grassland 4.7 Grassland - Subtropical/Tropical High Altitude

Threats
Major Threat(s):	The Eswatini highveld grassland areas are under pressure in many parts from ongoing heavy grazing by livestock and also by game within certain reserves.
List of Threats:	2 Agriculture & aquaculture 2.3 Livestock farming & ranching 2.3.2 Small-holder grazing, ranching or farming

Conservation Actions
Conservation Actions:	Four out of the nine known subpopulations for this species fall within Malolotja Nature Reserve so this species has a degree of protection. There are no recent collections for this species, the most recent is from 2013. However, it is a difficult species to identify and since natural habitat still remains it is suspected to be extant at most of the historically recorded sites. There is a need for further field surveys to improve the understanding of distribution and population trends.
