This study aimed to evaluate the phytosociology of the tree-shrub stratum of a segment of riparian forest in the Cutia Stream, in Boa Vista do Tupim, Bahia. Thirty-four transects of 50 m were allocated in the area with points established every 10 m. There were 816 individuals distributed in 64 genera, 28 families and 83 species. The largest IVI was from Astronium urundeuva (M. Allemão) Engl. (31.98%) and the Fabaceae family (79.01%), the most adapted specie was Colicodendron yco (Mart.) Mart. The density was 307 individuals.ha-1 and the basal area 10.6 cm2.ha-1. The Shannon-Wiener diversity index was H' = 3.484 and the Pielou evenness index was J'= 0.780. There was no prevalence of pioneer species in the area. Phytosociological information on the tree-shrub component can contribute to future ecological restoration projects or recovery of riparian forests in the middle section of the Paraguaçu Hydrographic Basin.
