Eriosema, comprising about 150 species, has a pantropical distribution, with two main centres of diversity, one in Africa and the other in the Americas. Currently 38 species are recorded for the Neotropics, of which 30 occur in Brazil. This work consists of the taxonomic treatment of the species of Eriosema in Southeastern Brazil. In this study, 26 taxa were recorded: Eriosema benthamianum, E. campestre var. campestre, E.campestre var. macrophyllum, E.congestum, E.crinitum, E.defoliatum, E. floribundum, E.glabrum, E. glaziovii, E.hatschbachii, E.heterophyllum, E.longiflorum, E.longifolium, E.obovatum, E.platycarpon, E.prorepens, E. pycnanthum, E.riedelii, E.rigidum, E.rufum var. macrostachyum, E.rufum var. rufum, E.simplicifolium, E.stenophyllum, E.strictum, E.tacuaremboense and E. tozziae. A new occurrence is cited for southeastern Brazil, E. tacuaremboense, besides the discovery of two new species, E. hatschbachii and E. tozziae.
