RESUMO

Abstract Galeandra (Orchidaceae) comprises about 18 species of epiphytic and terrestrial neotropical herbs. The genus is recognized by its flowers with funnel-shaped lip and spurred at the base. Four species of Galeandra have been recognized for the Argentinean flora in previous taxonomics studies: G. beyrichii, G. graminoides, G. hysterantha and G. styllomysantha. The aim of this contribution was to do a taxonomic treatment of Galeandra for Argentina. We recognize to G. beyrichii and G. xerophila, the last one is a new record for the argentinean flora. Galeandra graminoides and G. stylomisantha, are considered a doubtful report. The treatment includes an identification key, descriptions, geographic distributions data and habitat, field photographs, observations and comments on each species.
