Two species have been confused under the name Epidendrum brenesii Schltr., both were used in the original description and drawing of the type. The purple-flowered species, has been commonly known as E. brenesii, a specimen collected by Brenes close to the original locus typicus is therefore used to neotypify the species. The yellow-flowered species is described as Epidendrum sotoanum Karremans & Hágsater, in honor of the late Mexican botanist Miguel Ángel Soto Arenas.Two species have been confused under the name Epidendrum brenesii Schltr., both were used in the original description and drawing of the type.
