Abstract
A taxonomic revision of the genus Andropogon L. in Brazil is presented. Based on field collections, observation of the populations and revision of 72 national and international herbaria, 28 species, including A. Gayanus Kunth introduced from Africa were confirmed, besides one subspecie and one variety. The work includes key for the identification of the confirmed taxa, descriptions and illustrations, as well as data about geographic distribution, habitat, flowering periods, typification, synonymy and general comments.
