A phytosociological review is carried out of the pine forest formations on the islands of Cuba and Hispaniola (Caribbean), due to the diversity of soils and environments. We collected 10 plant associations belonging to the class Byrsonimo-Pinetea caribaea growing on siliceous, calcareous and sandy substrates and 21 associations on special, serpentine and ophite substrates and on ultramafic rocks belonging to the class Caseario crassinervis-Pinetea cubensis, exclusive to Cuba; while the association of pine forests on serpentines in Hispaniola is included in the class Phyllantho orbicularis-Neobracetea valenzuelanae with a Caribbean distribution. The comparative phytosociological and statistical study reveals phytosociological anomalies in the inclusion of various syntaxa, and in the description of other syntaxa according to the International Code of Phytosociological Nomenclature (ICPN). We therefore propose a change in status for several of the subassociations described: subass. ilicetosum repandae: syn. var. con Ilex repanda; subass. schmidtottietosum shaferi: syn. var. with Schmidtottia shaferi; subass. acrosynanthetosum trachyphylli: syn. var. with Acrosynanthus trachyphyllus; subass. psychotrietosum grandis: var. con Psychotria grandis; subass. notodonetosum roigii: syn. var. with Notodon roigii. We also propose a nomen novum: jaquinietosum oxhyphyllae Reyes & Acosta 2012 ex Cano et al. hoc loco.
