Justification: Previously known from only three disjunct locations, the botanical inventory work of the 1980s-90s identified the Kupe-Bakossi as highly important for this species, with six new locations from Bangem in the north to Nyale in the west and Mt Kupe in the east. It has not so far been collected on the slopes of Mt Cameroon or in neighbouring Nigeria and Bioko. The assessment of this taxon as Vulnerable made in Cheek et al. (2004: 141) is maintained here since the species is only known from ten locations, with an area of occupancy of 60 km² and an extent of occurrence of 18,032 km², and there is continuing decline in the extent and quality of the habitat it occurs i, especially at elevations below 1,000 m where there is extensive clearance for agricultural and urban expansion. |

Habitat and Ecology: | An understorey herb of mid-elevation to submontane forest, often near water; 50-1,500 m alt. |
Systems: | Terrestrial |
Continuing decline in area, extent and/or quality of habitat: | Yes |
---|
Major Threat(s): | As this species extends to forest below 1,000 m, it is threatened by widespread deforestation by agricultural (small-holder and agro-industry - coffee and banana) and urban expansion. |
Conservation Actions: | Protection of the remnant mid-elevation forest in Bakossi appears imperative for the survival of this species. Attempts should also be made to rediscover the disjunct populations in the southern parts of its range. |
