Platymiscium is included in the pantropical Pterocarpus clade of tribe Dalbergieae along with other woody genera with yellow petals. At the generic level, Platymisdum is unique within the Leguminosae by the presence of opposite leaves and interpetiolar stipules. Platymisdum is endemic to the Neotropics from Mexico through Central America to southern Brazil and Bolivia, occupying dry and wet forest habitats. The results of preliminary phylogenetic analyses support the hypothesis that Platymisdum arose in South America and radiated into Central America. Several species are highly valued for their wood by the timber industry throughout the Neotropics. The comparative morphology of Platymiscium species is investigated, reviewed and presented. Platymiscium comprises 19 species (29 taxa) of forest trees. Four species complexes consist of taxa widespread throughout South America, and 15 species are narrowly restricted endemics. All species are described and their distribution, phenology, habitat, vernacular names, uses, and conservation status discussed. One species, P. calyptratum M. Sousa & Klitg., is described as new. All 29 taxa are mapped, and 13 species (23 taxa) are illustrated. Keys are provided to all species and infraspecific taxa, and the treatment includes a full list of numbered exsiccatae. This forms part of the author's ongoing studies in the Pterocarpus clade.
