The present checklist used as base the list of lycophytes and ferns of São Paulo State, extracted from the Catálogo de Plantas e Fungos do Brasil published in 2010, by the Jardim Botânico do Rio de Janeiro (JBRJ). An update of this list is here presented and some novelties improved the base list. The current total number of taxa for the state, including both plant groups, increased from 561 to 573. Two new records were recently reported to the state and were also added to the present checklist (Pellaea flavescens Fée and P. ovata (Desv.) Weath.). These data suggest that more studies are necessary to know the diversity in the state.
