Plants up to 60 cm tall. Leaves 2–9, basal, villose on both sides, petiolate; petiole up to 10 cm long, commonly shorter basally imbricating; blade up to 13 cm long and 3.5 cm wide, oblanceolate to elliptic-oblanceolate, abruptly acuminate, gradually tapering into a conduplicate petiole. Peduncle erect, pubescent throughout, remotely few-sheathed, terminated by a subdensely many-flowered raceme 4.5–8.2 cm long. Flowers glabrous, sepals white with green or brownish veins, lip white with two green spots on the disc, and pink to red at tip. Floral bracts up to eight mm long, ovate to ovate-lanceolate, acute to subacuminate, sparsely villose. Pedicellate ovary up to l0 mm long, cylindric, densely villose. Dorsal sepal up to 12 mm long and three mm wide, lanceolate to narrowly elliptic-lanceolate, acute to subacuminate, primarily 3-veined. Petals unguiculate, claw free part up to three mm long, linear; blade up to 8.5 mm long and four mm wide, obliquely elliptic, basal auricle provided with a short, lobe-like protuberance overlapping blade, veins 2, branching. Lateral sepals up to 10 mm long and nine mm wide in total, united into a cochleate synsepal, more or less orbicular or elliptic-ovate in outline, bidentate at apex, principally 10-veined. Lip subsessile, up to 4.5 mm long and three mm wide, fleshy, cymbiform to deeply concave, oblong obovate in outline, acute to obtuse in front, basally provided with a transverse, replicate plate, the sides of which are abruptly decurrent onto lip. Gynostemium ca three mm long, robust, subsessile (Figs. 34 and 35).
Ecology: Terrestrial. In Colombia flowering in May, June, July, August, and November.
Distribution: Peru, Ecuador, Colombia. Alt. 2,450–3,000 m.

Notes: The most distinguished character of this species is the petal form, especially its basal auricle, acute, falcate and overlapping blade
