Inflorescence distinctly longer than the leaves, laxly c. 13-flowered; peduncle thin, 4.5 cm long; peduncle-scales c. 6, tubular, apiculate, in the basal part more closely spaced, to 0.35 cm long; rachis thin, 3 cm long. Floral bracts ovate-triangular, acuminate, sharply acute, to 0.23 cm long. Flowers small. Median sepal ovate, obtuse, concave, 1-nerved, 0.2 by 0.14 cm. Lateral sepals divergent, broadly obliquely ovate, acute, obliquely concave, 1-nerved, 0.2 cm long, including the mentum 0.25 cm long, 0.2 cm wide. Petals obliquely ovate, subacute, concave, 1-nerved, 0.16 cm long, 0.1 cm wide. Lip slightly sigmoid, clawed, concave, when flattened 0.14 cm long; claw quadrangular, at the base on either side with a small rounded lobule, probably with two glands, 0.07 cm long, at the base 0.06 cm wide, abruptly dilated into the blade, blade crescent-shaped-reniform, inside papillose and near the base with two convex thickenings, 0.06 by 0.18 cm, the lateral lobes obtuse, apex very broadly rounded, in the middle slightly retuse with a distinct obtuse lobule in the sinus. Column short, making an obtuse angle with the ovary, dorsally convex, papillose, without anther 0.08 cm long; clinandrium deeply concave; rostellum broad; stigma transverse, with raised margins; column-foot pointing backwards, 0.1 cm long, at the base appressed to the ovary and inside convex, in the apical part incurved, narrower than the basal part, truncate.
