Abstract

Odontadenia chapadensis J. F. Morales & I. L. Morais, a new species endemic to the states of Goiás and Tocantins, Brazil, is described. It resembles O. matogrossana J. F. Morales, from which it differs by its terete to subterete branchlets, smaller corollas, and puberulent ovary (vs. laterally compressed stems and glabrous ovary). Illustrations and a distribution map of O. chapadensis are included. The combination O. semidigyna (P. J. Bergius) J. F. Morales is made and a lectotype designated for its basionym, Echites semidigynus P. J. Bergius, and O. macrantha (Roem. & Schult.) Markgr. is reduced to synonymy.
