A terrestrial herb 2–6.5 dm. high, glabrous except for the roots.. Tubers ellipsoid to cylindrical-ellipsoid, 1.5–2.5 cm. long, 5–15 mm. in diameter, tomentose.. Stem erect, often somewhat flexuous, slender to rather stout, with leaves scattered along its length, terete or slightly angular.. Leaves 5–9, the lowermost often reduced to a sheath, the remainder ± adpressed or the lower ones somewhat spreading, lanceolate, acute, the largest 2.5–9 cm. long, 5–13 mm. broad, the uppermost similar to the bracts.. Inflorescence relatively short, 1.5–5.5 cm. long, 2–3.5 cm. in diameter, densely (l-)4-12(–16)-flowered.. Bracts broadly lanceolate, acute or acuminate, 1–2 cm. long, about equalling the pedicel with ovary.. Flowers suberect, pale yellow to deep orange; pedicel with ovary straight or slightly curved, 1–2 cm. long.. Dorsal sepal erect, very convex and forming a hood with the petals, broadly elliptical-ovate, 5–8.5 mm. long, 4.5–7 mm. broad; laterals deflexed, obliquely elliptical-or oblong-lanceolate, apiculate, 5–9 mm. long, 2–3 mm. broad.. Petals erect, adherent to the dorsal sepal, narrowly or ligulate lanceolate, curved, obtuse or subacute, 3.5–7.5 mm. long, 1–3 mm. broad.. Lip inflexed, ligulate or elliptical-ligulate, fleshy, convex, obtuse, 5–8.5 mm. long, 1–2 mm. broad.. Spur dependent, swollen in the apical half, 1–1.8 cm. long.. Anther erect, apiculate, ± 4 mm. high, loculi parallel, canals porrect, 2–3 mm. long.. Stigmas horizontal or slightly decurved, thick with swollen truncate ends, 2–3 mm. long.. Rostellum placed in front of the anther, the middle lobe narrow, acute, variable in length, sometimes overtopping the anther, the side lobes porrect with parallel sides.
