Petals obliquely elliptic, a little shorter but broader than the sepals, apex obtuse. Lip 3-lobed in the middle, 1.3 by 0.7 cm, semioblong at the base, with a narrow basal keel extending to beyond the middle; lateral lobes short, falcate-oblong, obtuse; midlobe much larger, 0.7 cm wide, elliptic, obtuse.
