A fragment of Semideciduous Submontane Forest, located in Viçosa from (20º35' to 28º50'S and from 42º45' to 43º00'W), Minas Gerais Southeastern Brazil, was studied to verify and analyze the changes that had occurred in its floristic composition between 1984 and 1998. All individuals with a trunk equal to or greater than 0.15 m of PBH of a phytosociological study were sampled in a grid plot of a hectare. In the 1998 survey, 94 species belonging to 77 genera and 32 families were sampled. Comparing the surveys of 1984 and 1998, it was observed that ten species were added to the experimental stand, with five of them being considered as initial secondary species and the other five as late secondary species.
