Flowers minute, c. 0.4 cm across. Sepals patent, oblong or elliptic, 0.2 cm long, subobtuse, glabrous. Lateral sepals oblique. Petals extremely small, obliquely oblong, obtuse, minutely papillose. Lip a little shorter than the sepals, 0.18 cm long, obovate-spathulate, broadly obtuse, 3-nerved, minutely papillose. Column rather thick, terete, almost three times longer than the petals, about 0.1 cm long, minutely papillose; clinandrium lobes dorsally abruptly bent backwards, lanceolate-triangular, subobtuse; rostellum erect, triangular, very small.
