Found in Carcih province of Ecuador and Piura department of Peru in cloud forests at elevations of 1600 to 3200 meters as a small sized, cool to cold growing terrestrial with fasciculate, stout, erect ramicauls enveloped by a loose, tubular sheath near the middle and 2 to 3 loose, imbricating, tubular sheaths at the base and carrying a single, apical, erect, thinly coriaceous, elliptical, acute to subacute, cuneate below into the subpetiolate base leaf that blooms in the winter and again in the summer on a secund, arising through a spathe from an annulus below the abscission layer, 6 to 9.2" [15 to 23 cm] long including the 3.2 to 4" [8 to 10 cm] long peduncle, densely and simultaneously many flowered inflorescence with an inflated, cucullate, obtuse, longer than the ovary floral bract.

"Characterized by the robust stature with inflated sheaths about the fasciled ramicauls. The stout, secund racemes of elongated flowers emerge from a large spathe at the base of the subpetiolate leaf. The base of each flower is contained within a large, inflated bract. The sepals, the longest of the subgenus, are multiveined. The petals and the lip are broadly obovate with rounded apices. The lip possesses only the transverse callus above the concavity of the lip."
