Checklist of lycophytes and ferns of Sao Paulo State, Brazil

The present checklist used as base the list of lycophytes and ferns of Sao Paulo State, extracted from the Catalog de Plantas e Fungos do Brasil published in 2010, by the Jardim Botanic 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 slate and were also added to the present checklist (Pellaea flavescens Fee and P ovata (Desv.) Weath.). These data suggest that more studies are necessary to know the diversity in the state.
