Raphia vinifera (Arecaceae; Calamoideae): Misidentified for far too long

Abstract:

Background The genus Raphia (Arecaceae/Palmae) is the most economically and culturally important genus of African palms. With over 20 recognized species, it is also the most diversified among tropical African palms. However, significant taxonomic confusion still persists in the genus. Raphia vinifera P. Beauv. is one of the first two names described in the genus, but the species has been misidentified and confused for several decades. New information We clarify the taxonomic identity of R. vinifera. We retrace the taxonomic history of the name and clarify its morphological identity using the literature and type material. We synonymize the name R. mambillensis with R. vinifera. We provide a new detailed morphological description of R. vinifera based on the study of herbarium material and field data. A distribution map is also provided. Raphia vinifera is still incompletely known, and more research should be undertaken on this species' presence and ecology, especially in West Africa.
