, and species are also found in the Greater and Lesser Antilles. This tribe consists of a group of understory and sub-canopy palms that populate both tropical lowland and montane forests. While members of this group are relatively easy to collect, as they are not canopy palms or spiny palms, and are well represented in herbaria, the taxonomy and phylogeny of the species within the tribe are still uncertain. The resolution of the tribe has been disputed despite the fact that Geonomateae species are characterized by three morphological
