Common Name The Deciever Masdevallia [refers to its being confused with another species]

Flower Size 3/8" [1 cm]

Found in Lara state of Venezuela, Antioquia and Cauca departments of Colombia and Morona-Santiago province of Ecuador at elevations of 1500 to 1900 meters in cloud forests as a miniature sized, cool growing epiphyte with stout, erect ramicauls enveloped by 2 to3 tubular sheaths carrying a single, apical, erect, coriaceous, elliptical, obtuse leaf that is narrowly cuneate below into the stout petiole that blooms in the winter, spring and fall on an erect to arching, arising from low on the ramicaul, congested, racemose, to 20" [to 50 cm] long, triquetrous, successively single flowered inflorescence with papery, imbricating, shorter than the pedicel floral bracts and carrying large showy flowers.

"Origianlly confused with M maculata but recognized by the large, slender, bilabiate flower borne in a congested, successively flowered raceme by a long, triquetrous peduncle. From the short sepaline tube the narrow dorsal sepal stands erect and the synsepal protrudes forward with revolute margins instead of decurving, the apices continuing as approximate, white tails."
