Lip immobile, porrect, strongly cymbiform-concave, from above oblong-elliptic, 0.73 by 0.33 cm; base with 2 small, short, longitudinal, parallel keels, with decurrent margins; margins strongly incurved near the apex, contiguous papillose; apex recurved, contracted, minutely 3-lobed, the lateral lobes angular-rounded, incurved, contiguous, the mid-lobe long, ovate, to the top somewhat contracted, obtuse, convex, underneath concave, when flattened oblong. Column curved, the base strongly thickened, laterally compressed, attenuate, 0.28 cm long; stigma longitudinal, narrowly linear; clinandrium concave, on either side of filament filiform, with a triangular tooth; stelidia strongly elongated, subulate, much longer than the anther, the base of the lower margin with a triangular, downwards pointing tooth, 0.1 cm long; column-foot almost absent. Anther cucullate, laterally compressed; connective thickly crested, papillose, apex thinly subulate-acuminate, 0.05-0.06 cm long. Pollinia subsemielliptic, laterally compressed.
