ABSTRACT
The genus Tropidia is composed of ca. 20-30 species distributed in southern Asia, South Pacific islands and northern Australia, and a single species occurring in America, from United States to Ecuador. The first record of the genus Tropidia for Brazil is presented here. It consists of Tropidia polystachya, a species found in the Cerrado biome, Midwestern Brazil. Description, illustration, photos, and distribution map of the species are provided. Additionally, the leaf anatomy of the species was studied and it is very similar to the leaves of other species of Tropidieae described so far. DNA sequences of T. polystachya are presented (plastid matK and rbcL and nuclear ITS) in order to assist future phylogenetic studies with the genus.
