Pseudobulbs greenish, broadly ovoid to depressed-conical, 0.8–1.2 cm in diam., 0.7-0.8 cm tall. Leaf petiolate; leaf blade coriaceous, oblong lanceolate, obtuse, (8)10–12(14) cm long, 1.2–1.4 cm wide, tapering into terete, shallowly grooved petiole-like base, 1.6-2 cm long. Inflorescence suberect to patent, long stalked, lax, many flowered secund raceme to 50 cm long; peduncle to 30 cm long, straight, glaucous light greenish, with few small sterile papyraceous scales; rachis to 25 cm long, glabrous, straight or slightly curved, with many flowers opening simultaneously. Floral bracts light dull yellowish, papyraceous, narrowly triangular, acuminate, 2–2.5 mm long, 0.8-1 mm wide. Pedicel and ovary 4-5 mm long, ovary obconical. Flowers spirally arranged, nodding, turned on one side, not widely opening, 5.5-6.5 mm across. Sepals dull yellowish, heavily striped with dark brown-purple, broadly incurved, narrowly oblong ovate, (5.5)6-7(7.5) mm long, lateral sepals 2.5-3.2 mm wide, median sepal distinctly narrower, all sepals obtuse, sometimes very shortly apiculate, dorsally glabrous, adaxially densely pubescent throughout with short hairs. Petals almost black, spatulate, 1.8-2 mm long, 0.8-1 mm wide, attenuate at the base, broadening and thickening to the triangular, obtuse apex, pubescent throughout apical half and long ciliate along margin. Lip almost black, fusiform narrowly obovate in outline, pouch-shaped, 4-4.5 mm long, 2-2.2 mm wide, recurved near the base, lip concavity ciliate along margin, green, with 2 low parallel black, shortly hirsute keels, lip apex almost half globular. Column white, shortly cylindric, broad, 1-1.2 mm tall, 0.8-1 mm wide, with little protruding stigma and small triangular, acute stelidia; operculum white, hemispheric, 0.5-0.6 mm in diam., finely papillose.
