The tribe Paniceae s.l. (Poaceae: Panicoideae) in the Reserva Biológica de Mogi-Guaçu, São Paulo State, Brazil

The present study aimed to survey the species of Paniceae s.l. in the Reserva Biológica de Mogi-Guaçu (RBMG-SP), located between 22°11'-18'S and 47°7'-10'W, in order to increase the knowledge of the grass flora of this conservation unit and of São Paulo State. The field trips were conducted between 2011 and 2012, comprising 11 expeditions. Specimens from the herbaria IAC, SP, SPF, and UEC were consulted. We confirmed the occurrence of 24 genera and 80 species for RBMG-SP. From these, 47 species are newly reported, 15 species are exotic, and 12 species are classified as threatened in the state. The richest genera are Paspalum (25 spp.), Panicum and Axonopus (7 spp. each), Digitaria (6 spp.), Ichnanthus and Urochloa (4 spp. each). Identification keys, comments, and images of the floral structures of each taxon are presented.
