Abstract

A new species of Stellilabium Schltr. is described and illustrated based on material collected in Colombia. The new species is most similar to S. morganiae Dodson, but differs from it in flower morphology. The gynostemium appendages of the new entity are ovate and widely spreading; in S. morganiae they are relatively small, not spreading, and oblong-ovate, and do not exceed the lip basal part in width.
