Sepals ovate, acuminate, about 0.95 cm long. Lateral sepals oblique, at the base dilated along the front margin. Petals obliquely elliptic-lanceolate, acuminate, glabrous, a little shorter than the sepals. Lip in basal part oblong-ligulate, dilated into a suborbicular, long acuminate blade, in the centre with a transverse double callus, as long as the petals, near the middle 0.5 cm wide. Column short, almost half as long as the lip, widened at the apex, clinandrium dorsally extended into a lobule, foot rather short. Anther reniform-cucullate, notched in front, glabrous. Ovary cylindrical, glabrous, subsessile, 2.5 cm long. (After Schlechter, 1911-1914).
