Resumen
The taxonomic history, general description and distribution are provided for Myoxanthus. Morphological characterization of
the vegetative and reproductive organs is illustrated with photographs. A list of the 52 accepted species includes synonyms
and distribution; most are illustrated with a flower photograph. Lectotypes for M. frutex, M. lonchophyllus, M. neillii, M.
pulvinatus, M. punctatus, and M. serripetalus are designated, and a neotype is selected for M. melittanthus. Myoxanthus
parvilabius is reported for the first time for Colombia. The circumscription of M. lonchophyllus is reevaluated, Pleurothallis
pennellia is recognized as a distinct taxon and transferred to Myoxanthus, and Myoxanthus panamense, a new species related
to M. scandens, is described from Pamana.
