Afterwards, a careful examination of specimens housed at main herbaria, along with the nomenclatural types, allows us to place it in Disododon, a monotypic genus previously known from East Africa. Disglodon sonkeanum Droissart, Stevart & P.J.Cribb, sp. nov. was collected in the lowland coastal forest of Atlantic Central Africa. It is known from a single locality in the surroundings of the Campo-Wan National Park. The species differs from D. comptum, by its several-flowered inflorescences, longer leaves and spur, and shorter pedicel and ovary. The species appears to be rare and is assessed as Critically Endangered [CR B2ab(iii)] according to IUCN Red List Categories and Criteria. New field investigations are required to attempt to find it in the low-elevation parts of the Campo-Ma'an National Park in Cameroon. 076 UR123 Cameroun
