ABSTRACT
This work is a taxonomic study of woody taxa of Papilionoideae in "cerrado" and seasonal semideciduous forest at the Estação Ambiental de Volta Grande. This environmental station is localized within the Triângulo Mineiro, to the southwest of the state of Minas Gerais, and belongs to the Companhia Energética de Minas Gerais, covering 391ha and portraying 30 years of natural regeneration. Fourteen taxa distributed in 11 genera and four tribes were reported for the subfamily. Dalbergieae, with Centrolobium, Dalbergia, Machaerium and Platypodium; and Sophoreae, with Acosmium, Bowdichia, Myroxylon and Ormosia were the most representative tribes, followed by Dipterygeae, with Dipteryx and Pterodon and Robinieae, with Sesbania. Three species of Machaerium, and two species of Acosmium were found, while the other genera were represented by one species each. An identification key, descriptions and illustrations are presented for the taxa studied, as well as comments regarding their geographical distribution.
