This taxonomic revision of the genus Dracaena L. (Liliaceae) in West Africa is another contribution towards a monograph on this group.Short general chapters contain historical, phytogeographical, morphological and phylogenetic observations. The taxonomic treatment contains a revised genus description, a key to the species in West Africa; 21 species are treated and illustrated, including 3 for the first time. Each species is fully described, typified and annotated pertinent to West Africa, with literature and synonymy. Distribution maps are added and specimens are cited with phenological data. Three continental African species were revised for their entire area; two additional species received token treatment.The validation of Dracaena cochinchinensis (Lour.) Bos (= Dracaena saposchnikowii Regel), correction of the name Palisota hirsuta (Thunb.) Schumann ex Engl., the presence of Dracaena draco (L.) L. in Senegal and the rejection of 8 names are appended.
