Found in La Paz department of Bolivia at elevations around 2200 meters as a miniature sized, cold growing, caespitose epiphyte with erect, stout ramicauls enveloped by a loose, tubular sheath below the middle and another at the base and carrying a single, apical, erect, coriaceous, narrowly elliptical-oblong, obtuse, cunaete below into the petiolate base leaf that blooms in the late spring and early summer on an erect, arising through a spathe from a node near the apex of the ramicaul, peduncle 3.2" [8 cm] long, rachis 8 to 11.6" [20 to 29 cm] long, erect, strict, congested, distichous, simultaneously many flowered inflorescence with oblique, acute, shorter than the ovary floral bracts and carrying yellow white flowers, that all face the same direction.

"This strong, caespitose species is known only from the orchid-rich region of the Zongo valley. The cauline sheaths are large and loose, and the spathe and floral bracts are proportionately long. The flowers are with round sepals that are arranged alternately in the same direction on a long, strict raceme. Three veins are barely visible in membranous petals without a transverse callus. The lip is shallow with the bar tall and erect with the dorsum sloping downward about half the length of the lip." Luer & Vasquez 2018
