Found in Amazonas department of Peru at elevations around 2200 meters as a mini-miniature, cold growing epiphyte with erect, blackish, slender ramicauls enveloped basally by 2 to 3 close sheaths and carrying a single, apical, erect, coriaceous, elliptical, obtuse, cuneate below into the elongate, blackish petiolate base leaf that blooms in the winter on an erect to ascending, slender, 2.4" [6 cm] long, as long as the leaf, single flowered inflorescence arising from low on the ramicaul.

"This species of SUBGENUS Masdevallia SECTION Masdevallia SUBSECTION Oscillantes Luer 1986 <, apparently endemic in Amazonian Peru, is related to the Ecuadorian M. andreettana. It differs from the later in the much less widely spread synsepal beyond the sepaline tube; larger, expanding wings of the lip; and a broad apex with the obtuse tip recurved." Luer 2001
