The leathery sepals are 10 mm long and concave toward the dilated acuminate end, where they are 2—3 mm wide. The filiform petals, also dilated toward the end, are 10 mm long and less than 1 mm wide. The lip
bears rounded lateral lobes, and divides into two triangular points at the apex. The callus is purple.
