Lateral sepals slightly oblique, towards the base slightly narrowed. Petals similar to the lateral sepals but a little narrower and more thin-textured, obtuse, glabrous, mid-vein thickened on inside. Lip obovate-cuneate, 1.5 by 0.9 cm, apex rounded, subretuse, in apical half with undulate margins, inside with irregular protuberances and in the apical half rough because of numerous warts; median keel linear, band-like, in front 3-dentate, glabrous, extending from the base of the lip to the apical fourth. Column slender, at the very base adnate to the base of the lip, glabrous, 1.1 cm long, dilated at the apex; clinandrium minutely denticulate. Anther deeply helmet-shaped, dorsally 3-lobulate, in front rounded. Ovary cylindrical, glabrous, c. 0.9 cm long. (After Schlechter, 1911-1914)
