This work aimed to characterize the foliar anatomy of 16 species belonging to 3 genera of the Malpighiaceae family found in Paraopeba s FLONA (MG) pointing out characters which may subsidize the genera delimitation, contributing by this way to the identification of species and construction of a dichotomous identification key used to identify taxa which includes the anatomic characters. The analyzed material was collected in the Paraopeba s FLONA and voucher material is kept at the VIC Herbarium at the Federal University of Vicosa MG, Brazil. Specimen samples from voucher material kept in herbariums at the Federal University of Brasilia (UB), University of Sao Paulo (SPF) and Rio de Janeiro Botanic Garden (RB) were used. The taxonomically characters considered to be the most import and that were used in the identification key for the Malpighiaceae species were: the presence and location of glands; presence of phloem in the medular region of the midvein; type of mesophyll; presence and type of trichomes; presence, quantity and disposition of the accessory bundles in the petiole. It was also possible to indicate promising characters for taxonomic and phylogenetic future studies in the Malpighiaceae family, especially for Banisteriopsis, Byrsonima e Heteropterys which belong to this family.
