This study aimed to generate floristic groups of trees in a fragment of Araucaria forest and determine the floristic associations and evaluate the horizontal structure and the floristic diversity of each formed group. The data were obtained from an experiment implemented in Faxinal Marmeleiros de Baixo locality in Rebouças - Parana. In an area of 509 ha, were installed 50 permanent sample plots of 500 m² (10 mx 50 m), distributed in a systematic way, where each individual tree with DBH less than 10 cm was measured and identified. Using multivariate analysis, the sample units with similarity in diversity indices for its species were grouped using cluster analysis. We obtained two floristic groups: Group 1, involving 38 sample units representing 64% of the area; Group 2, with 12 sample units representing 36% of the area. Through to sociological analysis were identified the species with the highest VI in each group, which were Curitiba prismatic (Group 1), Campomanesia xanthocarpa (Group 2). Group 1, present high number of species and most dominant, while group 2 has a higher species richness and most divercidade.
