Description:
Plant (10.8–)16.9–29.6(−35.7) cm high with the node of the uppermost sheathing leaf usually placed below ground level. STEM (3.0–) 3.6–5.4(−6.5) mm in diameter immediately below the inflorescence. Sheathing leaves (excluding cataphylls) (1–)2–3(−4); the longest one (4.8–) 8.2–14.8 (−17.7) × (1.0–)1.1–2.1(−3.1) cm, (2.7–) 5.0–10.3 (−14.4) times as long as wide, (0.2–)0.4–0.6(−0.8) times as long as the height of the plant, describing an adaxial angle of (5–)29–53(−70)° to the stem. Non-sheathing leaves below the inflorescence (1–) 3–5(−6). Inflorescence (3.3–) 4.3–7.0(−8.9) cm long, 0.2–0.3(−0.6) times as long as the height of the plant, carrying (5–) 8–13(−18) yellow flowers. Lamina of labellum usually provided with markings (but not beyond its proximal one-third), (6.3–)7.2–8.9(−9.9) × (7.6–) 9.2–11.0(−11.9) mm, slightly three-lobed [shape index (0.7–)0.8(−0.9), widest in its proximal to middle part, with the sidelobes describing an abaxial angle of (130–)141–180° to each other. SPUR nearly always straight to downcurved, (7.5–)8.3–10.4(−12.5) mm long, (1.0–)1.1–1.2(−1.4) times as long as the lamina of labellum, (2.0–)2.6–3.2(−3.4) mm in diameter at the entrance, (0.9–)1.0–1.4(−1.8) mm in diameter 1 mm
below the apex.
