Found in Atlantida department of Honduras, Zelaya department of Nicaragua, Puntarenas province of Costa Rica, Chiriqui province of Panama and Esmeraldas provincve of coastal Ecuador in scrub forests on small branches at elevations of 40 to 450 meters as a mini-miniature sized, hot growing, densely caespitose epiphyte with short, erct ramicauls enveloped by 1 to 2 tubular sheaths and carrying a single, apical, erect, coriaceous, elliptic-oblong, subobtuse, tridenticulate apically, attenuate below into the petiolate base leaf that blooms winter, spring and early summer on an erect, much longer than the leaf, to 3.6" [to 9 cm] long, racemose, distichous, densely many flowered inflorescence with adpressed, infundibular, obtuse, shorter than the ovary floral bracts and carrying the yellow and brown flowers in the upper third of the inflorescence.

"The plant is densely caespitose with thickly coriaceous leaves with abbreviated ramicauls completely enveloped by a loose sheath. The slender inflorescence far exceeds the leaves. In a congested raceme much shorter than the peduncle, the tiny flowers are borne transversely and ovarlapping in two opposite ranks. The oblong dorsal sepal is twice as long as the transversely obovate synsepal. The flabellate, single veined petals are not remarkable except that their width is thrice the length of the width of the lip. The nearly microscopic lip is thickly subquadrate with a concave glenion on the anterior face above the thickened, minutely apiculate margin. The stigmatic lobes of the column are small and inconspicuous behind the anther cap." Luer 2009
