ABSTRACT:

Rhaphidophora bogneri P. C. Boyce & Haigh is described as a new species from Gabon, equatorial West Africa, defined by inflorescences pendent during anthesis and fruiting. Rhaphidophora is additionally reviewed for Africa and three described species are accepted, of which R. africana N. E. Br. is considered undoubtedly polyphyletic, likely encompassing upwards of four species of which at least three are considered to be taxonomic novelties. Unfortunately, available preserved collections coupled with political circumstances prevailing throughout much of the species’ geographical range currently make a proper taxonomic treatment impossible. Rhaphidophora ovoidea A. Chev., described from fragmentary material from basalts, is treated as inadequately known. Rhaphidophora bogneri is illustrated from cultivated living plants, all described species are also illustrated from their nomenclatural types. The three accepted African Rhaphidophora species are delineated with a key.
