Revision of Drymophloeus (Areceacea: Arecoideae)

A revision of the genus Drymophloeus (Arecaceae: Arecoideae: Ptychospermatinae) recognizes seven species, distributed from the Maluku Islands of Indonesia to Western Samoa. The history of the genus is reviewed. A key, species descriptions, a complete list of synonymy, a list of specimens examined, illustrations and distribution maps are provided. A phylogenetic hypothesis is provided, as well as a discussion of biogeography. The new combination Drymophloeus hentyi is made to accommodate a species formerly included in the genus Ptychosperma.
