abstract = {Galeandra is a Neotropical genus with its center of diversity in the Amazon region. It comprises approximately 18 species of epiphytic or terrestrial herbs that are easily recognizable by their infundibular labellum. The present study examined the phylogenetic relationships between species of the genus Galeandra inferred with nucleotide sequences from five DNA regions - three plastid (psbA-trnH, rpoB-trnC, and trnG-S) and two nuclear (ITS and ETS). Matrices were analyzed individually and in a combined analysis using parsimony and maximum likelihood. We found that the epiphytic species G. devoniana is sister to the remainder of the genus, and that the other species form two groups - one epiphytic species and a second composed of terrestrial species. Adaptation to the terrestrial environment from a probable epiphytic ancestral was of great importance in the evolution of Galeandra. Furthermore, the infrageneric relationships found in this study differ from all previously proposed classifications.}
