Periandra Mart. ex Benth. is an essentially Brazilian genus comprising six species native to "cerrado" and "campo" vegetation. In this revision, the genus is separated into two subgenera: Periandra subg. Periandra and Periandra subg. Coccinea Funch & Barroso, based on macromorphological characteristics, approached in this paper, and palinological characteristics published earlier. None of the varieties previously proposed for P. mediterranea were accepted. One species, P. berteriana, does not seem to fit into the genus.
