Five Poaceae species (Gymnopogon burchellii, Ichnanthus bambusiflorus, Leersia ligularis, Merostachys neesii and Paspalum falcatum) legally considered as "presumably extinct" in the Brazilian state of São Paulo were found during field work undertaken in several sites of the construction of the ring-road "Rodoanel Mario Covas" and Serra da Bocaina region. It is suggested that these species names be taken out from the extinct species list and be placed in a category compactible with the present knowledge on the conservation status of these species in the state of São Paulo.
