The species-rich neotropical tree genus Swartzia (Leguminosae-Papilionoideae) is a ubiquitous element in Central and South American rainforests. As such, it has been selected as a focal group in ongoing studies of the evolution and assembly of the neotropical flora, but these efforts are hindered by substantial taxonomic problems within Swartzia. The lack of a well-substantiated infrageneric classification has impeded much needed revisionary work on the genus, since the composition and limits of the various species complexes of Swartzia have not been clearly defined. A recent phylogenetic study of Swartzia with broad sampling of molecular characters and species illustrates the deficiencies of previous classifications of the genus and provides a robust phylogenetic framework for devising a new classification. Here we propose a phylogenetically based classification that places all currently recognized species of Swartzia into 15 sections. The sections, ranging in size from one to thirty-two species, are morphologically diagnosable and are hypothesized to be monophyletic. Thirteen sectional names are either entirely new or are applied at the sectional rank for the first time. A key to the sections is provided, along with sectional treatments that each include a morphological description, geographic distribution, and list of included species.
