RESUMO
The study of Leguminosae Mimosoideae is part of the project Flora of Serra do Cipó, Minas Gerais, Brazil, which aims to provide identifcation keys, illustrations, comments on geographic distribution and phenology to genera and species from this region. Field and herbaria studies indicate that Mimosoideae is represented in the area by 57 species belonging to 13 genera: Abarema (2 spp.), Albizia (1 sp.), Anadenanthera (1 sp.), Calliandra (6 spp.), Enterolobium (1 sp.), Inga (6 spp.), Leucochloron (1 sp.), Mimosa (25 spp.), Piptadenia (3 spp.), Plathymenia (1 sp.), Pseudopiptadenia (2 spp.), Senegalia (4 spp.) and Stryphnodendron (3 spp.). Te exsicattae of Mimosa macedoana, one of the species occurring at the rocky felds of the region, show two morphotipes distinguished by the size of their vegetative parts. aiming to investigate whether this distinction also happens in the natural environment, two populations of the species were submitted to a morphometrical analysis using multivariate statistical methods (LC, PCa &DF). results showed that the populations are morphologicaly distinct, and that physiographic caracteristics of the rocky outcrops where the populations grow may infuence the morphological variation.
