Resumo
The affinities of the Ocotea species from Cuba are examined based on sequences of the nuclear ITS region and the chloroplast psbA-trnH spacer, supplemented by SEM studies on stomatal morphology. The species with bisexual flowers, all of them endemic either to the Greater Antilles or Cuba only, form (at least) two phylogenetically distinct groups. Ocotea bucheri, O. libanensis, O. moaensis, O. reticularis, and an undescribed species, all of them endemics of Eastern Cuba, form the sister group to the genus Damburneya. The remaining species form two clades nested in the Praelicaria clade. It remains uncertain if these two clades are sister to each other or not. The two widespread dioecious species show the expected affinities to conspecific material from other parts of the Neotropics.
