The present work is a survey of the taxa in the tribe Andropogoneae (Panicoideae - Poaceae) that occur on the Island of Santa Catarina, Florianópolis, Brazil. Based on a review of herbarium specimens and fieldwork, 20 species were recorded in the following 10 genera: Andropogon L. (7 spp.), Bothriochloa Kuntze (2), Eriochrysis P. Beauv. (1), Hyparrhenia Andersson ex E. Fourn. (1), Imperata Cirillo (1), Ischaemum L. (1), Rhytachne Desv. (1), Saccharum L. (3), Schizachyrium Nees (2) and Sorghum Moench (1). Seventeen of the species are native, and two species are subspontaneous. Bothriochloa and Rhytachne are recorded here, for the first time, for the Island of Santa Catarina. This work provides key to the genera and species, as well as illustrations, information about geographic distribution, habitat, phenology, and comments about each taxon presented in the study.
