Rhizome very short, roots elongated, filiform, flexuose, glabrous. Stems crowded, erect, laterally compressed, unbranched, 30-45 cm long, densely many-leaved.

Petals sublinear-ligulate, a little shorter than the sepals, apex obtuse. Lip 3-lobed in apical fifth, 1 by 0.5 cm, hypochile oblong, with a backwards-pointing, low, conical, obtuse basal callus, margins minutely subserrate; lateral lobes very indistinct; epichile triangular-semi-elliptic, inside with 4 median transverse folds, obtuse.
