Campylocentrum Benth. (Orchidaceae, Epidendroideae) in the Federal District and Goiás State, Brazil

Abstract

Campylocentrum Benth. has a neotropical distribution and about 73 species arranged in five sections. In Brazil, it is represented by 38 species (24 endemic), concentrated mainly in the Atlantic Forest. In order to contribute to the taxonomic knowledge of the genus in Cerrado areas of Central Brazil, where it is not studied, we provide a taxonomic treatment for species occurring in the Federal District and in the Goiás State. Five taxa were recorded arranged in three sections: C. kuntzei Cogn. ex Kuntze, C. mattogrossense Hoehne (C. sect. Campylocentrum Cogn.), C. neglectum (Rchb.f. & Warm.) Cogn. (C. sect. Laevigatum E. Pessoa & M. Chase), C. fasciola (Lindl.) Cogn. and C. pachyrrhizum (Rchb.f.) Rolfe (C. sect. Dendrophylopsis Cogn.). Of these, C. fasciola constitutes a new occurrence for the flora of Goiás. Here we provide an identification key, descriptions, taxonomic and geographic distribution comments, in addition to images and illustrations are presented.
