Abstract

During the study of Microchilus (Goodyerinae, Orchidaceae) for Brazil, a problem regarding the systematic positioning of the name Pelexia pauciflora was identified. This name was sometimes considered to belong to the subtribe Spiranthinae, and while at other times it was placed within Goodyerinae. After examining the type materials and studying the protologs, we concluded that this taxon belongs to Spiranthinae, with Eltroplectris pauciflorus as the correct name to use. Furthermore, we discuss and propose the second stage of lectotypification for this name, along with the synonymization of Eltroplectris guimaraesii under E. pauciflorus.
