This work was carried out in a Submontane Semideciduous Forest fragment stretch on São Geraldo Farm, in Viçosa (20º45'23"S and 42º52'23"W), Cwa climate type, Zona da Mata, Minas Gerais, Brazil, to determine the floristic composition of the tree stratum and make some inferences about its respective ecological groups. The floristic listing was taken from a phytosociological survey in which 158 point-centered-quarters were employed. Ten surveys carried on the Zona da Mata were analysed to determine the main species of the region. A total of 632 individuals with a minimum trunk circunference of 0.15 m at 1.30m above the soil were sampled, comprising 123 species, 85 genera and 36 families. According to the ratios of the species distributed over the ecological groups, the fragment under study was classified as being at an intermediary stage of regeneration. Amongst the species observed, some are considered endangered species not only in the state of Minas Gerais but also in Brazil.
