Abstract
Due to knowledge gaps on the genus Coryanthes from the state of Mato Grosso, is provided a taxonomic study of the species from the state, including ecological, historical and taxonomic comments. Four species of the genus are treated: C. speciosa rediscovered in the state after 87 years of Frederico Carlos Hoehne's expeditions; C. dasilvae and C. macrantha new records to the Central-Western region of Brazil and C. wenzeliana recently described species, known only from the type specimen. During this study we also discovered that the type of C. macrantha was destroyed, and a lectotype for this name was designed here.
Key words:
Cerrado; Cymbidieae; Epidendroideae; flora; Amazon Forest
