Abstract

Ten species and one variety of Roystonea are recognized from in and around the Caribbean basin. Species are circumscribed on the bases of morphological characteristics. A cladistic analysis suggests that some previously recognized subgenera and sections were artificial or metaphyletic. The following nomenclatural changes are made: Roystonea oleracea var. jenmanii comb. nov. and R. maisiana stat. nov. /// Se reconozen diez especies y una variedad de Roystonea en la cuenca del Caribe y áreas circumvecinas. Las especies se circumscriben en base a sus características morfológicas. Un analysis cladístico indica que algunos subgeneros y secciones previamente propuestos son artificiales y parafyléticos o metafyléticos. Se hacen los siguentes cambios nomenclaturales: Roystonea oleracea var. jenmanii comb. nov. y R. maisiana stat. nov.
