Found in Cauca department of Colombia at elevations around 1600 to 2000 meters as a miniature sized, cool to cold growing epiphyte with erect, stout ramicauls enveloped by a 2 tubular sheaths and carrying a single, apical, erect, coriaceous, oblong-ligulate, obtuse, cuneate below into the petiolate base leaf that blooms in the fall on an erect, secund, 2” [5 cm] long including the .8” [2 cm] long peduncle, subdense, many flowered inflorescence arising through a slender spathe from an annulus below the apex of the ramicaul with cucullate, acuminate floral bracts.

"Vegetatively, this small species resembles other species, such as Stelis braccata Rchb.f. & Warsz. From these it is easily distinguished by three-veined petals and the distinctive lip. The lip is triangular in lateral view, with a two-humped bar uppermost, the dorsum being acutely deflexed from the anterior surface." Luer 2018
