Among Euphorbiaceae, the genus Manihot stands out primarily by its taxonomic complexity. It is a Neotropical genus with 98 species distributed from Texas to Argentina. In Brazil, the region of Planalto Central, especially the states of Minas Gerais and Goiás,and the state of Bahia in the Northeast region can be considered the centers of diversity forthe taxon. The aim of this study was to prepare a monograph of the genus Manihot in São Paulo State. Ten species of the genus Manihot were found: Manihot anomala Pohl, M. caerulescens Pohl, M. fruticulosa Pohl, M. gracilis Pohl, M. grahamii Hook., M. inflata Müll. Arg., M. jolyana Cruz, M. pilosa Pohl, M. procumbens Müll. Arg., and M. tripartita (Spreng.) Müll. Arg. In this synopsis, it is proposed that M. jolyana Cruz and M. handroana Cruz would be treated as a single species, therefore,we propose the synonymization.
