Found in Zamora Chinchipe Ecuador, Peru and Bolivia in cloud forests at elevations around 3100 to 3350 meters as a medium sized, cold growing terrestrial or epiphyte with caespitose to slightly creeping on a bracteate rhizome and giving rise to ovoid pseudobulbs enveloped completely by 8 to 10, distichous, uppermost leaf-bearing sheaths and carrying a single apical, erect, obovate, acuminate, conduplicate below into the subpetiolate base leaf that blooms in the winter on an erect to arching to sub-pendent, almost straight, to 28" [70 cm] long, paniculate, widely spaced, to [18 cm] long, to 10 flowered side branches, many flowered inflorescence with adpressed, scale-like bracts.

Cyrtochilum tetraplasium is often cited as the correct name for this species but it can be separated by the dorsal sepal that is distinctly bent forward and basally parallel to the column, the narrower lip, the different calli, and the wider and less erect column.
