This study presents a floristic survey of the Leguminosae family in the Parque Ecológico Paulo Gorski, a natural reserve in the western of the state of Paraná, south of Brazil and aimed to contribute to the improvement of the knowledge of the Legumes Flora in that state. Field collections were undertaken between October/2007 and December/2008, along the main trails. We found that Leguminosae was represented by 29 species in 26 genera. Senna was the most representative genus, comprising three species, followed by Desmodium, with two species. The other genera were represented by a single species. This work includes identification key, descriptions, comments, geographic distribution, phenology and illustrations of the species.
