Abstract: We studied the floristic composition and structure of the arboreal component (trees, palms and ferns with DBH equal to or greater than 4.8 cm) of two plots of Lower Montane Rain Forest in Ubatuba, SP, one with a history of selective logging and the other more preserved. We sampled 50 families, 114 genera and 193 species (four undetermined). The richest families were Myrtaceae, Fabaceae, Lauraceae, Rubiaceae, Melastomataceae and Sapotaceae. In the disturbed plot we sampled 104 species, 72 genera and 39 families, and in the more preserved area, 152 species, 98 genera and 43 families. There were differences in species richness, in the prevalence of their succesional status and in the structure of the areas, and the multivariate analysis allowed recognition of two floristic blocks. Among all species, 33 were exclusive of the first plot and 95 were exclusive of the second plot. Almost half of the species (45%) occurred with only one or two individuals and 29 have some degree of rarity. Five species are in the category of vulnerable in the List of brazilian plant species threatened of extinction. The differences observed between the sites studied, as well as the occurrence of rare and endangered species highlight the importance of the conservation of the area.
