: The genus Hoffmannseggia Cav., now recognized as a monophyletic group distinct from Caesalpinia and Pomaria, consists of 22 species and is amphitropically distributed between North and South America, with 11 species in arid and semi-arid areas of the southwestern USA and adjacent Mexico, and 12 species in southern South America. Recent publications have provided a revision of Hoffmannseggia for North America, a resolved phylogeny an analysis of the biogeography of the genus, but there is to date no treatment of all of the taxa in the genus. Here we present a key to the genus and its closest relatives, a key to all of the recognized taxa, typification, distributional data for each species, selected specimens examined for the South American taxa, and notes where appropriate. Keywords: Caesalpinia, Caesalpinieae, Hoffmannseggia, Fabaceae, Leguminosae. : Caesalpinia, Caesalpinieae, Hoffmannseggia, Fabaceae, Leguminosae.
