During field expeditions on white sand patches in northwestern Maranhão, Brazil, we found specimens of Calea characterized by minute florets and pappuses, common to Calea divaricata clade species. After thorough analysis, we concluded that those specimens represent a new species, which is described here as Calea breviflora. Its description, distribution map, illustrations, taxonomic comments, information on the habitat and a preliminary conservation assessment are provided. Moreover, we present an identification key for the Calea divaricata clade species.
