The purpose of this study was toevaluate the composition and structure of three different types of grasslandvegetation of Southern Brazil. We aimed to discuss the floristic similaritiesamong these areas and the influence of the Cerrado flora in their composition. Thestudy was conducted in the Parque Estadual de Vila Velha (PEVV) (25o12´34"-25o15´35"S and 49o58´04 "-50o03´37"W), Municipalityof Ponta Grossa, Paraná State, Brazil, in three grassland physiognomies: dry(CS), wet (CU) and rocky (CR). Thirty plots of 1 × 1 m were placed in each areafor the quantitative sampling. Additionally, species that occurred around theplots were also collected. In total, 283 species were sampled, with 163 speciesin CS, 87 species in CU, and 59 in CR. 36.48% (85) of the species sampled inthis study also occur in the Cerrado. The cluster analysis showed that thefloristic composition of the three grassland areas is significantly differentdue to several factors, especially the soil water system.
