More than 200 collaborators are involved, mostly from the State of São Paulo, with the contributions of researchers from other states and from abroad. Since 2001, seven books with monographs of 151 families were published, dealing with 3,237 species within 722 genera. This project was the starting-point of the gathering of information about the diversity of spermatophytes of the State of São Paulo. The current checklist, at this point, presents an updated and virtually complete list of species, all certified by specialists. It also contains references to scientific collections for most of the taxa (vouchers) or to bibliography referring to the natural or subspontaneous occurrence of the species in the State. The list now contains 7,305 species distributed in 1,776 genera and in 197 spermatophyte families (according to Cronquist 1981) or 195 (according to APG III). 23% of the 31,728 species of spermatophytes listed in the Flora of Brazil occur in São Paulo State. The most representative families are Orchidaceae (797 species), Asteraceae (676 species), Fabaceae (513 species), Poaceae (500 species), Myrtaceae (304), Rubiaceae (265 species) and Melastomataceae (253 species), which, altogether, accumulate 3,308 species and constitute 45% of total species of spermatophytes in the state. The wealth of the Brazilian plant diversity, partially expressed in São Paulo, shows how important is the continuity of floristic studies in a country that is very likely to hold the largest plant diversity in the planet.}, number={4}, journal={Biota Neotropica}, author={Shepherd, George John and Estrada, Tiago Egger Moellwald Duque and Koch, Ingrid and Pirani, José Rubens and Harley, Ana Maria Giulietti and Kinoshita, Luiza Sumiko and Magenta, Mara Angelina Galvão and Wagner, Hilda Maria Longhi and Lohmann, Lúcia Garcez and Amaral, Maria do Carmo Estanislau do}, year={2011}, month={Dec.} }
