This study presents the floristic and structural composition of vegetation islands of an inselberg in Vale do Moxuara, in Cariacica-ES, to evaluate whether the islands' richness is related to their size and soil depth. A total of 45 vegetation islands were evaluated by estimating the phytosociological parameters needed for the analysis. Fifty-three vascular plant species of twenty-four families and forty-eight genders were found. The most outstanding families were Poaceae, with seven species, followed by Malvaceae and Fabaceae, with six species each. Weeds represented 39.6% of all flora listed and 25.5% of the islands' vegetation cover. Selaginella convoluta and Anemia tomentosa had the most frequency and relative cover. Multiple regression was not significant, considering the inhibiting role played by the weed species.
