== Taxonomy == In 1841, John Lindley used the name Hormidium for one of the subgenera into which he divided the genus Epidendrum. He described the subgenus as having pseudobulbous stems, sessile flowers and with the lip (labellum) of the flower joined (adnate) to the column. Later, in 1861, Heinrich Reichenbach concluded that the subgenus Hormidium was superfluous.
