Taxonomic synopsis of the genus Senna (Leguminosae, Caesalpinioideae, Cassieae) in Central-West Region of Brazil. Analyses of herbaria material, specialized literature, and fieldwork revealed the occurrence of 75 taxa corresponding to 36 species, four subspecies and 32 varieties of the genus Senna in the Midwest Region. Mato Grosso and Goiás with 26 and 25 species respectively were the states where the genus was more representative followed by Mato Grosso do Sul and Distrito Federal with 23 and 18 species each. Twelve species were common to the four states in the studied region, five (S. corifolia, S. neglecta, S. pentagonia, S. rostrata e S. uniflora) were found only in Goiás, five (S. macrophylla, S. latifolia, S. paraensis, S. quinquangulata e S. tapajosensis) in Mato Grosso, two (S. hilariana, S. paradictyon) and S. septemtrionalis in the Federal District. Identification keys, illustrations with diagnostic characters of taxa and comments on the geographical distribution of them are presented.
