In this work we present a floristic survey of the fern families Grammitidaceae and Polypodiaceae occurring in "Parque Estadual das Fontes do Ipiranga" (PEFI), located in São Paulo, SP, Southeastern of Brazil. Grammitidaceae is represented in the area by only one genus and one species: Micropolypodium achilleifolium (Kaulf.) Labiak & F.B. Matos, while Polypodiaceae is represented by 15 species, classified into six genera: Campyloneurum (C. nitidum (Kaulf.) C. Presl), Microgramma (M. percussa (Cav.) de la Sota, M. squamulosa (Kaulf.) de la Sota, and M. vacciniifolia (Langsd. & Fisch.) Copel.), Pecluma (P. paradisae (Langsd. & Fisch.) M.G. Price, P. truncorum (Lind.) M.G. Price, and P. singeri (de la Sota) M.G. Price.), Phlebodium (P. areolatum), Pleopeltis (P. astrolepis, P. hirsutissima, and P. pleopeltifolia), and Serpocaulon (S. catharinae, S. meniscifolium, S. sehnemii, and S. vacillans). We also present keys to identify the genera and the species, as well as description, geographical distribution, comments, and illustrations for some taxa.
