Plants up to 35 cm tall. Leaves 1–3, basal, rosulate, subsessile, up to 20 cm long and 4.5 cm wide, elliptic to lanceolate-elliptic, acute to acuminate, hirsute throughout. Peduncle slender, villose, 2–3-sheathed, terminated by a loosely many-flowered raceme. Flowers large, glabrous, white with greenish stripes on sepals and brownish red stripes on petals. Floral bracts up to 10 mm long, ovate-lanceolate, acute to acuminate, villose. Pedicellate ovary up to 30 mm long, filiform, villose. Dorsal sepal 13–18 mm long, two to three mm wide, lanceolate, acute to acuminate, 5–9-veined. Petals unguiculate, claw free part ca three mm long; lamina 13–17 mm, 2.3–3 mm wide, ligulate to ligulate-triangular, with obtuse to rounded angles and cuneate base, veins 2, branching. Lateral sepals 13–20 mm long, 11–25 mm wide when spread, obliquely elliptic to elliptic-ovate, obtuse at apex, connate together to the middle or above, quadrate-flabellate in outline, concave at base. Lip unguiculate, claw ca one mm long, thickened, terete; lamina 2.5–3 mm long, 1–1.5 mm wide, linear-crescent-shaped from lateral view, linear-lanceolate, basally provided with a pair of conical to subglobose calli giving a subcordate appearance, apex acute. Gynostemium ca two mm long, long-stalked (Fig. 36).
Ecology: Terrestrial. Flowering in May and October. Distribution: Ecuador, Colombia. Alt. 3,000 m. The occurrence of this species in Colombia was provided by Dodson (1992), Ortiz Valdivieso (1995), Ortiz Valdivieso & Uribe Vélez (2007), and Bernal, Gradstein & Celis (2015).
Notes: The unique character of this species is its linear-lanceolate lip lamina, basally provided with a pair of conical to subglobose calli giving a subcordate appearance.
