Lateral sepals obliquely triangular, obtuse, concave, slightly more than 0.1 cm long, 0.15 cm wide; mentum short, obtuse, 0.03 cm long. Petals obliquely ovate, at the apex recurved, subobtuse, 1-nerved, 0.08 cm long, almost 0.05 cm wide. Lip slightly sigmoid, concave, broadly spathulate, 0.13 cm long, 3-nerved; claw broad, slightly dilated at the base, claw slightly more than 0.05 cm long; blade transversely rhombic, 0.1 cm wide, in front broadly and indistinctly 3-lobulate, with broadly obtuse apex, the lateral angles obtuse.
