Pollen morphology of 37 taxa belonging to 15 genera in Arecaceae are described to elucidate previous studies and relations among taxa. Though Arecaceae are an eurypalynous family, West Indian species usually show a homogeneous pollen type: simple, monosulcate, medium-size, tectate-perforate or semitectate; however, grains are trichotomosulcate or monosulcate (dimorphic) in Pseudophoenix sargentii, Gastrococos crispa and Bactris cubensis or exclusively trichotomosulcate in Acrocomia aculeata. Trilete impression was found in Coccothrinax salvatoris and C. litoralis which is a difference when compared to C. argentata. Pollen grains in Coccothrinax miraguama and C. yuraguana differ in exine thickness, whereas Calyptronoma shows a definitive palynological homogeneity belonging to a Calyptronoma plumeriana pattern. The importance of exine stratification as the definitive character in palynological determination of species is verified. Palynological results corroborate the Moya & Leyva (2000) proposal of an up-to-date checklist of Cuban Palmae.
