The Mimoseae tribe has 41 genera and about 860 species, and is one of the four tribes of the Mimosoideae subfamily, which belongs to the most diverse family of Brazilian flora, Leguminosae. This research had as object the taxonomic study of Mimosae’s tribe genera and species that occurs on Espírito Santo. Every collection of the State, and the RB, were consulted. The field work to observation and gathering of plants happened between april/2014 and july/2015. Descriptions, morphological diagnosis, illustrations and maps were elaborated. Comments about geographic distribution, reproductive phenology, morphological variation and taxonomy were made. The extrafloral nectary were described and analyzed. Identification keys for the genera and species based on vegetative and reproductive characters, and a key with extrafloral nectary characters are presented. On Espírito Santo, there are nine genera and 45 taxa: Anadenanthera (2 spp.), Leucaena (1 sp.), Mimosa (21 spp.), Parapiptadenia (1 sp.), Parkia (1 sp.), Piptadenia (6 spp.), Plathymenia (1 sp.), Pseudopiptadenia (7 spp.) and Stryphnodendron (3 spp.).
