État de la populationTexte officiel évaluation IUCNExpert
This species was recorded from one location in 1982, and again in 2000, but no details of population size were recorded. It was found again in 2022 and 2023. Most recently, the plants were found in small clusters spread out over an area of about 100 m by 20 m. There are between 500 and 1,000 mature individuals within the only known population. The population trend is stable.

Description complète des menacesTexte détaillé évaluation IUCNExpert
The location where this plant was found falls within a forestry plantation, but on an unplanted area, maintained as a firebreak. Provided that this area is not planted up, the current land use provides some measure of protection. There is livestock grazing in the area, but as the plants grow amongst rocks, this would protect them from grazing to some degree. There is also a future potential threat from the development of road infrastructure since the site occurs adjacent to a public road that leads to a border post and therefore it could be upgraded.

Mesures de conservation recommandéesStratégies de conservation IUCNExpert
Raising awareness with the plantation management of the presence of this species and the management actions to maintain it would assist with its conservation. Ex situ conservation of this species is a high priority due to it being only known from one location. One ex situ collection is recorded (BGCI 2022). This would require maintenance of live plants, as it is believed to be recalcitrant and therefore not suited to storage of seed.
