État de la populationTexte officiel évaluation IUCNExpert
No quantitative population data are available for this species. It is known from four herbarium specimen collections and one sight record dating from 1956 to 2007. The population is known to be declining, with only larger specimens (those with flowers) visible, and largely restricted to the steepest slopes and near-vertical cliffs (T. Rulkens pers. obs. 2019).

Description complète des menacesTexte détaillé évaluation IUCNExpert
This species is threatened by a continuing increase in fire frequency on Mt Zembe, which is resulting in the destruction of plants particularly at the immature stages (T. Rulkens pers. obs.). There are also plausible future threats to this species. There has been some quarrying of rock for construction materials at the foot of Mt Zembe, and whilst this is not considered to be a major threat at present, it may expand in the future and threaten this species. There is also a potential threat of over-harvesting by plant collectors for private collections and for the horticultural trade.
