The moist grassland phyto-physiognomy associates with the Cerrado biome near springs and streams, and in areas with shallow groundwater. This vegetation has a very typical flora, due the particular soil conditions that restrict and select species. The main objective of this study was to record the species of vascular plants in moist grassland in Fazenda Pedra Vermelha, at Analândia municipality, São Paulo, and to compare the floristic composition with other wetlands areas in Brazil. The area has 5ha and is located between the coordinates 22°07'50-08'01S and 47°46'40-53O, and at altitudes ranging from 760 to 770m. The floristic survey was carried along 18 months. A total of 178 species, 121 genera and 62 families were registered in the area. Asteraceae (19 species), Cyperaceae (15), Poaceae (14) Melastomaceae (13) Xyridaceae and Eriocaulaceae (8) were the richest families. A probable new species of Cyperaceae was diagnosed and seven endangered species were found. The floristic similarity between this sampled moist grassland and the compared areas was low. The results show a significant floristic richness of the moist grassland at the Fazenda Pedra Vermelha.
