Found in Napo and Pichincha provinces of Ecuador at elevations around 1500 meters as a medium sized, cool growing epiphyte or terrestrial with cane-like, arcuate, elongate, slender, unbranched, basal half leafless, apical half 5 to 7 leaved stems carrying stiff, plicate, prominently 11 to 13 veined, distichous, ovate-elliptic, long-acuminate, sessile leaves that blooms in the spring and fall on a terminal, with one to two reduced leaves subtending the base, cylindric, densely many flowered inflorescence with cymbiform, acute, as long as the ovary floral bracts and carrying pale pink flowers with a brown apical spot on the lip.
