Abstract
Paepalanthus Mart. comprises approximately 400 species, mainly distributed in South and Central America, with center of diversity located in the Espinhaço Range, in Minas Gerais and Bahia. In a taxonomic point of view, Paepalanthus is the most complex genus of Eriocaulaceae and the lack of floristic studies hinders the improvement of its circumscription. In this context, it was carried out the Paepalanthus flora of Biribiri State Park, which is located in Diamantina Plateau, in Minas Gerais state. In the area, the genus is represented by 33 species. Identification key, descriptions and illustrations, as well as comments about morphology, habitat, geographic distribution and phenology are presented.
