Justification:
Despite the relatively large altitudinal range and extent of occurrence of this species, it is rare throughout, being known from only seven locations, those in Nigeria, Rio Muni and S. Province, Cameroon, from early 20th century collections. This taxon is also possibly known in Cameroon from Mevou southeast of Ebolowa (S. Province) and from 5 km N.W. of Yaoundé (Central Province), the determination of these collections is still to be confirmed. The total area of occupancy is likely to be less than 2,000 km², and there is continuing decline as the sites in Nigeria and the lowland site(s) in S. Province, Cameroon, are under threat from forest clearance for agriculture and logging.

Habitat and Ecology [top]

Habitat and Ecology: Occurs in closed-canopy lowland to submontane and montane forest; ca. 200–2,000 m alt.

D. viridiflora is very close to D. mildbraedii, an uncommon taxon of Rio Muni with which D. viridiflora was treated as synonymous before a taxonomic revision in 1984. However, it is still possible that D. viridiflora is under-recorded due to confusion with this sympatric species.
Systems: Terrestrial

Conservation Actions [top]

Conservation Actions: Continued protection of the submontane and montane forest on Mt Kupe; a survey of the population of this taxon here will help determine how important a site this is for conservation of this taxon.
