Found in Bolivar province of Ecuador at elevations around 2500 meters as a small to medium sized, cold growing, caespitose epiphyte with stout, erect ramicauls enveloped by a close, tubular sheath below the middle and 2 to 3 others at the base and carrying a single, apical, erect, coriaceous, elliptical, subacute, petiolate base leaf that blooms in the early summer on 2, erect, arising from a node .2" [5 mm] below the apex of the ramicaul through a slender spathe, peduncle .4 to .8" [1 to 2 cm] long, 4 to 6.4" [10 to 16 cm] long overall, strict, congested, distichous, successively few, many flowered inflorescence with as long as the ovary floral bracts and carrying yellow, not expanded flowers.

"This tall, strong, caespitose species of SECTION Stelis is distinguished by a pair of crowded, distichous racemes of small, yellow, half-closed flowers with a coarse, white, pubescence filling the interior. The petals are broadly triangular, overlapping the sides of the column and corners of the lip. The stigmatic lobes are round and in apposition below the stigma. The lip, probably a variation of type A, is rounded at the apex and concave below a cleft bar. " Luer 2013
