Flower Size .2" [5 mm]

Found in Norte de Santander department of Colombia at elevations around 2600 meters as a mini-miniature to miniature sized, cold growing, caespitose epiphyte with slender, erect ramicauls enveloped by a tubular sheath below the middle and another at the base and carrying a single, apical, erect, coriaceous, elliptical, obtuse to rounded, cuneate below into the petiolate base leaf that blooms in the fall on a single, erect, arising through a slender spathe from a node below the apex of the ramicaul, peduncle .8 to 1.6" [2 to 4 cm] long, suberect, flexible, subflexuous, distant, distichous, loose, rachis 4.8 to 6" [12 to 15 cm] long, successively 1 to 3, several flowered inflorescence with oblique, acute, as long as the ovary floral bracts and carrying dull purple flowers.

"This medium-sized, caespitose species is distinguished by rather large flowers in a loose, subflexuous raceme longer than the leaf. The leaves are obtuse to nearly rounded at the tip; the sepals are subacute with a long, fine pubescence; and the large petals are semilunate and concave with a narrow margin. The lip is thick with the dorsum deflexed from the transverse bar and extending nearly the length of the lip." Luer 2017
