Lateral sepals oblique, towards the base along the front margin strongly dilated. Petals obliquely suborbicular, obtuse, 0.25 cm long. Lip as long as the sepals; claw ligulate-cuneate; blade about as long as the claw, semioblong, obtuse; spur oblongoid obtuse, porrect, almost a third as long as the lip. Column short; rostellum much overtopping the clinandrium; stigma hidden by a transverse lamella. Anther suborbicular, apiculate; pollinia obliquely obovoid; stipe linear; viscidium round. Ovary subsessile, clavate, 0.45 cm long. (After Schlechter, 1911-1914)
