ABSTRACT
The taxonomic study of herbaceous, shrubby and climibing members of the Leguminosae in seasonal forests of the Itacolomi State Park (PEI) was based on monthly collections from September 2004 to November 2005. The study area included eight trails, distributed in submontane, montane and upper montane seasonal forests, where 30 species distributed in 20 genera were found. Of the three subfamilies represented, subfamily Papiliononideae was the richest both in terms of genera (12) and species (18). The most representative genus was Senna with three species, followed by Bauhinia, Acacia, Inga, Piptadenia, Crotalaria, Dalbergia, Desmodium and Machaerium with two species each. Calliandra, Mimosa, Aeschynomene, Chaetocalyx, Camptosema, Clitoria, Dioclea, Indigofera, Poiretia, Trifolium and Vigna were represented by just one species. Identification key, descriptions, illustrations and comments about phenology, taxonomy and distribution are provided.
