A terrestrial herb 2–4 dm. high, glabrous except for the roots.. Tubers ellipsoid or globose, 1–2 cm. long, 8–16 mm. in diameter, densely tomentose.. Stem erect, rather slender, leafy along its entire length.. Leaves 6–11, ascending or suberect, the 2–4 lowermost sheath-like, the middle ones narrowly lanceolate or almost linear, not much narrowed to base, acute, the largest 5–11 cm. long and 5–17 mm. broad, the uppermost 1–3 much smaller, lanceolate, acuminate.. Inflorescence 6–19 cm. long, 2–4 cm. in diameter, rather loosely to densely 10-to many-flowered.. Bracts lanceolate, acuminate, 1–2.5 cm. long, longer than the pedicel with ovary and sometimes longer than the flowers.. Flowers suberect or ± spreading, green or yellowish-green; pedicel with ovary curved, 10–15 mm. long.. Dorsal sepal erect, ovate or elliptical-ovate, rounded at the apex, convex, 4–7.5 mm. long, 2.5–4.5 mm. broad; laterals defiexed, obliquely lanceolate, subacute, 5.5–8.5 mm. long, 2–3 mm. broad.. Petals bipartite nearly to the base; posterior (upper) lobe curved-ligulate, acute, 4.5–7.5 mm. long, ± 1mm. broad; anterior lobe curved upwards, 4–11mm. long, longer or shorter, but always much narrower, than the posterior.. Lip defiexed or pendent, 3-lobed from an entire base 1.5–2 mm. long; middle lobe ligulate or broadly linear, 4.5–9.5 mm. long, ± 1 mm. broad; side lobes variously longer or shorter than the middle lobe but only half as broad.. Spur dependent, 7–16 mm. long, somewhat swollen in the apical half.. Anther 1.5–2 mm. high, rounded at apex, canals slightly incurved, scarcely 1 mm. long.. Stigmas decurved on to the base of the lip, narrowly club-shaped, 1.5–2.5 mm. long.. Rostellum very broadly triangular, obtuse.
