Found in La Paz department of central Bolivia in cloud forests at elevations of 2000 to 2200 meters as a mini-miniature, cold growing epiphyte with erect, slender ramicauls enveloped basally by 2 to 3, thin, tubular sheaths carrying a single, apical, erect, coriaceous, elliptical, subacute leaf that gradually narrows below into the petiole and blooms in the spring on an erect, arising from low on the ramicaul with a bract near the base, terete, congested, .4" [1 cm] long, successively few flowered, racemose inflorescence with tubular, shorter than the pedicel floral bracts.

"The terete peduncle produces a successively few flowered raceme of orange and purple, long-tailed flowers that resembles M bicolor of SECTION Alaticaules with a stout, triquetrous rpeduncle. In SUBGENUS Polyantha SECTION Polyanthae SUBSECTION Successiviflorae Luer 2000 it is closely allied to the short-tailed M menatoi." Luer 2000
