Flower Size .12" [3 mm]

Found in La Paz department of Bolivia at elevations around 2000 meters as a mini-miniature sized, cool to cold growing, caespitose epiphyte with erect, slender ramicauls enveloped by a tubular sheath below the middle and 1 to 2 others at the base and carrying a single, apical, erect, coriaceous, narrowly elliptical, acute, cuneate below into the petiolate base leaf that blooms in the early summer on an erect, arising from a node near the apex of the ramicaul, peduncle .4" [1 cm] long, rachis 2" [5 cm] long, subflexuous, distichous, subcongested, simultaneously several, to 10 flowered inflorescence with oblique, acute, longer than the ovary floral bracts and carrying dark red-purple flowers.

"This small, caespitose species is characterized by narrowly elliptical leaves, and an equally long, distichous raceme of dark red-purple flowers. The sepals are broadly obtuse and each three-veined. The lip is most remarkable with a tall, rounded callus on the dorsum that divides the bar on its descent through the center of the lip." Luer & Vasquez 2018
