Common Name The Outstanding Masdevallia

Flower Size 3/4" [2 cm]

Found in Morona-Santiago and Zamora-Chinchipe provinces of Ecuador in cloud forest at elevations of 1500 to 2300 meters as a small sized, caespitose, cool to cold growing epiphyte and occasional terrestrial with stout erect ramicauls enveloped basally by 2 to 3 loose, tubular sheaths carrying a single, apical, oblanceolate leaf tapering to a long petiolate base that blooms in the spring on a slender, with a basal bract, erect, 10" [25 cm] long, successively few, triquetrous, single flowered inflorescence and a tubular, shorter than the pedicel floral bract carrying the distant flowers, each occuring well above the previous and all held above leaf height.

"Charaterized by a broad, petiolate leaf and an exceeding long peduncle. The raceme of a few distant flowers is reminiscent of M aenigma, but the raceme of the later is shorter and more congested, often with 2 simultanoeus flowers borne by a shorter peduncle. The sepaline tube of the later is also much shorter. The similar yellow dorsal sepal and purple synsepal of M excelsior are connate into a very short cup beyond which the synsepal expands. All three tails are long and slender. The petals are oblong with a callous swelling at the base of the lamella along the margin. The lip is subpandurate with broadly obtuse, marginal folds and the tip of the epichile is acuminate-apiculate." Luer 2000
