État de la populationTexte officiel évaluation IUCNExpert
This species was first collected in 1999 at two disjunct localities 170 km apart in western Cameroon: between Laikom and Fundong in Boyo Division, and near Kodmin in the Bakossi Mountains. It was recorded as locally common at the latter site. Two further collections were made in 2001 in the Bali Ngemba Forest Reserve. Further sub-populations are likely to exist at localities that have not yet been included in botanical inventories, given the large areas of grassland at altitudes of around 1,500 m in the Bamenda Highlands, Bamboutos and, to a lesser extent, in Southwest Region (B. Pollard pers. obs. 2004).

Description complète des menacesTexte détaillé évaluation IUCNExpert
The species is threatened as a consequence of trampling by cattle and other livestock, and deliberate burning of the montane grasslands in the Northwest Region is thought to result in subpopulation losses or may lead to long-term habitat changes which do not favour this taxon. In the Bakossi National Park lack of human disturbance may lead to forest encroachment and hence a population decline.

Mesures de conservation recommandéesStratégies de conservation IUCNExpert
Studies of the subpopulations in the Northwest Highlands could be made to better understand the ecology of this taxon, including its tolerance of fire and human disturbance. This species should also be searched for in suitable habitat elsewhere in western Cameroon; discovery of further subpopulations would lead to a downgrading of its conservation status.
