Justification:
This species, known from four locations, has a restricted distribution with an extent of occurrence (EOO) of 1,028 km2 and an area of occupancy (AOO) of 16 km2.  There is ongoing degradation of its habitat from the spread of alien invasive plant species and small scale agriculture.  Based on this, it has been assessed as Endangered under Criterion B.
History: -
Geographic Range
Range Description: Originally known only from the type locality in the Lubombo Mountains in Eswatini, this species has since been located in Mpumalanga, north of Eswatini, and in the Goba area in Mozambique, east of the Eswatini border.
Countries: Native:
Eswatini; Mozambique; Mpumalanga;
Population
Population: It has been observed to have subpopulations of 20 to 50 mature individuals at each locality in South Africa, and is reported as abundant locally at the type locality in Eswatini. It is inferred that the population is declining due to habitat loss as a result of the spread of invasive alien plant species and small scale agriculture.
Population Trend: Decreasing
Habitat and Ecology
Habitat and Ecology: This species is found in grassland on mountain slopes, on gentle to steep slopes, on stony/rocky soil, in full sun. It requires burning as a part of their life cycle.  It has been found in two vegetation types, Southern Lebombo Bushveld (SVI16) and Kaalrug Mountain Bushveld (SVI12) (Mucina et. al. 2018).
List of Habitats: 2 Savanna
2.2 Savanna - Moist
Threats
Major Threat(s): There is a potential threat of the spread of Eucalyptus species at one location in South Africa, and the Eswatini and Mozambique subpopulations are likely to be at risk from the spread of the alien invasive plants, namely Chromolaena odorata and Lantana camara. The Mozambique population is also threatened by livestock grazing, trampling and subsistence farming.
List of Threats: 2 Agriculture & aquaculture
2.1 Annual & perennial non-timber crops
2.1.2 Small-holder farming
8 Invasive and other problematic species, genes & diseases
8.1 Invasive non-native/alien species/diseases
8.1.1 Unspecified species
8.1.2 Named species
8.1.2 Named species
Conservation Actions
Conservation Actions: The currently known distribution for this species does not include any conservation areas.  The plants favor low altitude grassland of which very little is formally protected. No material has yet been collected for ex-situ conservation, and more fieldwork is required to determine the extent of this plant's distribution and abundance as well as to determine population trends.
List of Conservation Actions: 1 Land/water protection
1.2 Resource & habitat protection
3 Species management
3.4 Ex-situ conservation
3.4.2 Genome resource bank
