Abstract	The objective of this study was to adjust and select probability density functions that characterize the diametric structure of this forest fragment and for the species: Cedrela fissilis, Luehea divaricata, Gochnatia polymorpha, Sebastiania commersoniana and Casearia sylvestris for a 15.24 hectare fragment of Mixed Ombrophylous Forest, located in Curitiba, State of Parana. In order to evaluate the diametric distributions of this forest and the five selected species, seven probability functions were adjusted for 5cm class intervals. According to the criteria of selection adopted, the model that best represented the diametric distributions for the whole forest, Cedrela fissilis, Gochnatia polymorpha and Sebastiania commersoniana was the Weber model; for Casearia sylvestris, the Gamma function (adapted) was the most efficient, and for Luehea divaricata, none of these functions showed adherence. The Sebastiania commersoniana, Luehea divaricata, Casearia sylvestris and the forest as a whole showed inverted "J" or decreasing distribution, while, Cedrela fissilis and Gochnatia polymorpha showed an almost unimodal distribution with a strong asymmetry to the right.
