Lateral sepals connate into a broadly oblong, in front shallowly incised synsepal, 0.7 cm long, 0.4 cm wide at the middle, at the base concave. Petals obliquely falcate, somewhat spreading, oblong, subacute, O.7 cm long, above the middle 0.2 cm wide. Lip in outline pandurate, 0.6 cm long, at the base saccate-bilobed, in the middle narrowed, with incurved margins, apical part ovate, acute, with undulate margins. Column subclavate; rostellum erect, keeled in front, apex notched; stigma only slightly raised. Anther at base cordate, apex obtusely acuminate, in front with a somewhat fleshy, obtuse median keel; pollinia clavate-pear-shaped; stipe linear, short, sparsely puberulous; viscidium minute.
