État de la populationTexte officiel évaluation IUCNExpert
There have been varying reports of the number of plants remaining in the wild. The type population has apparently been completely extirpated (D. Goode pers. comm.) and relatively few plants were known from a second locality. Surveys undertaken by KwaZulu-Natal conservation authorities failed to find any plants (B. Church pers. comm. 2011) but there are unconfirmed reports that 4–5 plants may still exist in the wild.

Description complète des menacesTexte détaillé évaluation IUCNExpert
This species has been severely affected due to over-collection of plants from the wild for ornamental purposes. The few remaining plants, if any are left, are unlikely to represent a viable population and the species is potentially functionally extinct in the wild.

Mesures de conservation recommandéesStratégies de conservation IUCNExpert
This species is listed in Appendix I of the CITES Appendices. Formal protection of the remaining plants and a re-introduction programme must be implemented. A Biodiversity Management Plan was published in 2017 which identifies several initial actions including surveys to locate remaining plants.
