Abstract:
:Lyroglossa and Pteroglossa (Orchidaceae: Spiranthinae) are first recorded for Rio Grande do Sul. Descriptions, illustrations, taxonomic notes and distribution are presented. We also provide an artificial key to distinguish the genera of the "Stenorrhynchos Clade" reported so far in Rio Grande do Sul.
