Sumario:Taxonomic studies of the genus Marsypianthes Mart. ex Benth. (Hyptidinae, Lamiaceae) in Brazil. Marsypianthes Mart. ex Benth is a neotropical genus which occurs from south Mexico to Argentina’s northeastern part. The genus is composed by six species: M. arenosa Brandegee, M. burchellii Epling, M. chamaedrys (Vahl) Kuntze, M. foliolosa Benth., M. hassleri Briq. and M. montana Benth. The last five ones species (M. burchellii, M. chamaedrys, M. foliolosa, M. hassleri and M. montana), object of this study, occur in Brazil and three of them (M. burchellii, M. foliolosa and M. montana) are endemic to the country. Goiás state is the center of the genus diversity, which is represented in this state by four species: M. burchellii, M. chamaedrys, M. foliolosa and M. montana. These ones are distributed, primarily, in the rupestrian formations of Cerrado, in the riverbanks, in open places with greater intensity bright and are associated with sandy soils, sandy-stony soils, clayey and humid ones. M. hassleri species occurs in Argentina, Paraguay and south of Brazil, and M. chamaedrys, widely distributed, occurs from south Mexico to Argentina. Among the species, M. burchellii is endemic to Chapada dos Veadeiros and features yellow corolla and strongly vinaceous calyx, while M. chamaedrys, with prostrate or decumbent habit, occurs in disturbed soil and is the only one that does not present xylopodium. Marsypianthes foliolosa is easily recognized in field by unmistakable smaller leaves and by the lower number of bracteoles and flowers’ cyme. Marsypianthes hassleri shows stigma’s position above the anthers, differing from the other species mentioned, and occurs in southern Brazil. Marsypianthes montana is herb of caespitose growth. This dissertation presents descriptions, identification key, illustrations, genus and species’ distribution maps, vulgar names quotes and each species habitats.
