Lateral sepals divergent, obliquely oblong, upper 3/5th part gradually narrowed, acute, concave, 3-nerved, 0.54 by 0.2 cm; lower margin except at the base incurved. Petals very small, oblong, oblique, obtuse, 1-nerved, 0.17. by 0.08 cm; base dilated; margins minutely crenulate. Lip with a very short, membranous claw inserted on the column-foot, slightly recurved, from above linear-oblong, fleshy; base in the basal extended into a backwards-pointing, dorsally compressed, truncate appendage as long as the claw; in the basal part with dilated, erect, rounded margins, channelled-concave, in front convex, obtuse; underneath strongly channelled, pilose, 0.25 by 0.06 cm. Column 0.15 cm long; stelidia parallel, elongated, subulate, slightly curved, much longer than the anther; stigma obovate; column-foot making an obtuse angle with the ovary, incurved, oblong, concave, in cross-section especially near the apex triangular, its apex free and on either side dilated in a rounded lobule, 0.08 by 0.06 cm at the apex.
