Abstract
This study presents the taxonomic treatment of woody Leguminosae in seasonal forests of Itacolomi State Park (PEI). Botanical material was collected monthly, from September 2004 to November 2005, along eight trails in submontane, montane and upper montane seasonal forests. Woody Leguminosae were represented by 39 taxa in 22 genera distributed among the three subfamilies: Cesalpinioideae (9 species), Mimosoideae (17), and Papilionoideae (13). The most representative genera were Inga (8 species), followed by Machaerium (4), Senna and Dalbergia (3 each), Abarema, Anadenanthera, and Tachigali (2 each). Bauhinia, Cassia, Copaifera, Melanoxylon, Calliandra, Mimosa, Piptadenia, Pseudopiptadenia, Stryphnodendron, Andira, Bowdichia, Ormosia, Platypodium, Pterocarpus, and Swartzia were represented by one species each. Ormosia friburgensis and Tachigali friburgensis are reported for the first time in Minas Gerais state. Analytical key, descriptions, illustrations, data on phenology, and comments on taxonomy and preferred habitat in PEI are provided for all taxa.
