A floristic survey of Papilionoideae species was carried out in "campos ferruginosos" of Itacolomy State Park (PEI), situated between Ouro Preto and Mariana cities, Minas Gerais. The collections was made from March, 2001 to May, 2002. Twenty species of 13 genera of Papilionoideae were identified. The genera that had more representative number of species were Desmodium (4), Crotalaria (3), Machaerium (2) and Stylosanthes (2). The others had only one specie each. In the phenological study of the species, correlations between environmental parameters (temperature and rainfall) and the leaf fall, leaf flushing, flowering and the fruiting were verified.
