Inflorescences (up to 6 present at the same time) successively many-flowered, with flowers opening one by one, pendent, gradually elongating, to 9–28 cm long; peduncle gradually widening towards the rachis, 1–2 cm long; rachis flattened, 0.2–0.3 cm wide, the axis fractiflex, but the rachis almost straight because of the differential width of the flattened tissue; distance between successive flowers on the same side of the rachis 0.5–0.8 cm; floral bracts conduplicate, narrowly triangular in lateral view, subacute, c. 0.2 cm long. Flowers not opening widely, minute. Pedicel and ovary terete, glabrous 0.4 cm long. Sepals and petals mutually connate in basal half.

Petals 0.15 cm long, free part ovate, 0.9 by 0.55 cm; apex subacute; 1-nerved. Lip 0.33 cm long from the apex to the tip of the spur; blade elliptic, when not flattened 0.13 by 0.05 cm, concave, with erect margins, at the apex more fleshy, with two flat calli separated by a groove, obtusely apiculate; spur 0.2 cm long, 0.09 cm high in lateral view, somewhat incurved, obliquely saccate, laterally flattened, much narrowing towards the mouth, at the almost truncate apex with a broad umbonate concavity, inside, at the apex of the concavity, but on the other side of the spur wall, with a bilobed, wart-like callus. Column 0.06 cm long; laterally with indistinct, arm-like processes. Anther cucullate, 0.05 cm long, smooth; pollinia not seen. Fruit not seen.
