A New Species of Cyrtopodium (Orchidaceae) from the Cerrado of Central Brazil

ABSTRACT Cyrtopodium macedoi, a new species (Orchidaceae, Cymbidieae, Cyrtopodiinae) from the cerrado vegetation of central Brazil, is described and illustrated. The species was first collected in 1951 but was subsequently misidentified as C. vernum. The principal distinctive character for C. macedoi is the basal portion of the corolla lip and the region between the lateral lobes, which is strongly deflexed and almost parallel to the lip midlobe. Cyrtopodium macedoi appears to be rare and so far known only from two sites in the Triângulo Mineiro region of the western part of the state of Minas Gerais in southeastern Brazil.
