This study was developed in a section of a Montane Seasonal Semideciduous Forest fragment,
in the Bom Sucesso Farm, Viçosa – MG – Brazil. This study aimed at finding out about the floristic composition
and the phytosociologic structure of the tree component. Ten transects of 50x10m, subdivided into 5 plots
of 10x10m each, totalling 50 plots within 5000m2 were established. In the sampling, all the tree individuals
with a minimum of 15cm of stem circunference at 130cm above ground were evaluated. A total of 151 species
pertaining to 108 genera of 45 botanic families were identified. Within 0.5 ha, 820 alive trees and 32 dead
standing up trees were sampled, which means a total density of 1704 individuals/ha. The basal area/ hectare
was 38.450m2 and the average height was 8.43m. The species Euterpe edulis was prominent in the structure
of the studied vegetation, with 314 individuals sampled, resulting in a relative density of 37.38%, absolute
frequency of 90%, relative frequency (FR) of 8.91%, relative dominance of 18.79%. The Shannon diversity
index was 3.52 and the equability was 0.696. The result of floristic composition and phytosociologic structure
showed high richness and medium diversity, although most of the species were represented by few individuals.
