Range DescriptionRecorded from Cameroon S.W. Province: Mt Kupe (1 site, 3 collections), Bakossi (1 collection at Bangem, recorded but not collected elsewhere), Mt Cameroon (1 site, 2 collections), Littoral Province: Mt Nlonako (1 collection), W. Province: Bangou nr. Bangwa (1 collection).
This taxon was originally described in 1892 based upon 2 specimens from Buea, Mt Cameroon, from where it has not subsequently been collected and may be extinct. However, it has since been recorded in the 1960s at Bangou and in the 1970s on the western slopes of Mt Nlonako. Inventory work in the 1990s revealed this species to be locally abundant above Nyasoso on the western slopes of Mt Kupe; it has also been collected at Bangem and recorded flowering elsewhere in the Bakossi Mts (M. Cheek, pers. obs.). This species is sometimes locally gregarious, as recorded on Mt Kupe and on Mt Nlonako, where Letouzey recorded it as "abundant".
