The study was carried out from the analysis of specimens deposited in herbaria. Field expeditions were carried out to observe the species in their habitat, to obtain photos and new collections. It was recognized in São Paulo, 23 species of Ochnaceae: Ouratea (17), Quiina (two, previous published) and Sauvagesia (four). A brief diagnosis, etymology of specific epithets, taxonomic and ecological comments, identification keys, photos and species distribution maps are presented.
