Petals similar to the lateral sepals but a little narrower, 1.25 cm long, subacute, glabrous. Lip curved, in outline elliptic, 1 by 0.4 cm, subobtuse, minutely papillose, in basal half with two parallel, obtuse, almost glabrous keels. Column semiterete, slightly curved, 0.85 cm long, not widened at the apex; clinandrium dorsally widened, semiorbicular, denticulate, glabrous. Ovary slender, cylindrical, 0.8-0.9 cm long, glabrous.
