A terrestrial herb 2-5 dm. high, glabrous except for the roots; tubers ellipsoid or almost globose, 0.5-2 cm long, 5-12 mm in diameter, sparsely tomentose. Stem erect, often somewhat flexuous, slender, terete, with leaves scattered along its length. Leaves 6-10, the lowermost 1-2 reduced to sheaths, the remainder suberect or ± spreading, the largest 2.5-6 cm long and 4-9 mm broad, the upper smaller. Inflorescence short, rarely up to 5 cm long, 2.5-3.5 cm in diameter, densely 2-5(-7)-flowered. Bracts broadly lanceolate, acuminate, 7-20 mm long, shorter than the pedicel with ovary. Flowers curving outwards or suberect, orange; pedicel with ovary somewhat curved, 1.5-2.5 cm long. Dorsal sepal erect, broadly ovate, very convex, acute, 7-11 mm long, 5-6 mm broad; laterals defiexed, obliquely oblong-lanceolate, acute, 8-10 mm long, 2-3.5 mm broad. Petals erect, adherent to the dorsal sepal, much curved, ligulate-lanceolate, 7-10 mm long, ±2-5 mm broad. Lip defiexed, 3-lobed at the base, 6.5-10.5 mm long, 1-2 mm broad, the side lobes tooth-like or triangular, spreading, scarcely 1 mm long; spur dependent, swollen in the apical third, 1-1.7 cm long. Anther erect, apiculate, 3-5 mm tall, canals porrect, 1-2 mm long. Stigmas horizontal, thick, club-shaped, 2-3 mm long; rostellum erect, nearly as long as the anther, the middle lobe narrowly triangular, just over 2 mm long, the side lobes truncate, shorter.
Leaves 6–10, spaced along stem, the lowermost 1–2 sheath-like, the rest ± spreading, the largest 2.5–6 × 0.4–0.9 cm, narrowly lanceolate, the upper ones becoming bract-like.
Stigmatic arms 2–3 mm long, horizontal, clavate; rostellum almost as long as anther, mid-lobe c. 2.5 mm long, side lobes c. 1.2 mm long, truncate.
Lip deflexed, 6.5–10 × 1–2 mm, with 2 tooth-like lobes c. 0.5 mm long at the base; spur 9–17 mm long, swollen at apex, usually tucked into bract.
Dorsal sepal erect, 7–11 × 5–6 mm, ovate, acute, convex; lateral sepals deflexed, 8–10 × 2–3.5 mm, obliquely lanceolate.
Terrestrial herb 20–50 cm tall; tubers 5–20 × 5–12 mm, ellipsoid or ± globose, sparsely tomentose.
Petals erect, 7–10 × 2–3 mm, curved-lanceolate, adnate to dorsal sepal.
Anther 2.8–5 mm high, erect, apiculate; canals 1–2 mm long, porrect.
Inflorescence compact, less than 5 cm long, densely 2–5(7)-flowered.
Ovary and pedicel arched, 15–25 mm long, the bracts shorter.
Flowers bright orange, including ovary.
