Specimens from the Maxillaria graminifolia suballiance (here redefined) were examined with 50 flowers analyzed from SEL, AMES, and MO. From 26 published names including 14 basionyms, six species from the Maxillaria graminifolia complex are recognized. Three basionyms of R. Schlechter, of which no types have been located, are tentatively placed among the accepted species. The earliest name in the group, Isochilus graminifolium Kunth, has been misapplied. A specimen intermediate between specimens of two other accepted species is interpreted as a natural hybrid. From this study some unique vegetative characters are identified for convenient field identification in addition to unique distribution ranges (i. e., Central America vs. South America). Range maps and complete exsiccati are cited. A key to accepted species is provided.
