Abstract
(now ) was described from South America and reported to be a widespread tropical plant in both Africa and the Americas. A revision of herbarium material revealed that leaf shape differs between the populations of the Eastern and Western Hemispheres. Therefore, we maintain the name s.str. for the American populations and re-instate the name for most of the African plants. Both species are found in tropical evergreen forests, mainly at low altitudes. Furthermore, two mountain species, from Madagascar and from east tropical Africa, which were previously identified as , are described as new to science. Compared to both and , these new species have short inflorescences and longer, recurved or uncinate perianths in the fertile flowers and morphologically resemble ; the latter is only known from the mountains of Equatorial Guinea (Bioko Island), south-west and (newly recorded here) North-West Regions of Cameroon. The species under study are compared with one another and with the related, pantropically distributed species ; their synonymy is verified and typifications are established. The fine-level partial florescence (cyme) structure of each species is also studied, with further taxonomic implications. seems to be restricted to west and central tropical Africa, with its range replaced eastwards by and in Madagascar by .
