Part Shade Cold Spring

Common Name The Windowed Masdevallia [refers to the window-like patch of translucent tissue near the base on each side of the sepaline tube]

Flower Size 2" [5 cm]

Found in Huanuco department of Peru at elevations around 3000 meters as a small sized, cold growing caespitose epiphyte or terrestrial with erect, slender ramicaul enveloped by 3 to 4 tubular sheaths and carrying a single, apical, erect, coriaceous, elliptic, obtuse, basally conduplicate and cuneate into the long petiolate base leaf that blooms in the spring on an erect, terete, peduncle [.48 to .52" [12 to 13 cm] long, rachis .8" [2 cm] long, successively single, 2 to few flowered inflorescence with adpressed, tubular, shorter to as long as the pedicel floral bracts

"Masdevallia fenestralis appears most closely related to Masdevallia carmenensis Luer & Malo in addition to Masdevallia fenestrellata, which all share a deeply tubular flower. But M. fenestralis differs in the overall much larger size, and with a flower twice as large as M. carmenensis (ca. $" [10 cm] versus ca. 2" [5 cm] long). Masdevallia fenestralis differs from the following new species by the white and purple, internally pubescent flower, versus an overall smaller sized plant, with a smaller white and glabrous flower."
