Lateral sepals glabrous, connate in their basal part and forming a collar around base of spur, falcate, linear, widened in basal part, 1.7-1.8 by 0.3 cm, obtuse, conoid-acuminate, 3-nerved at base, 5-nerved in higher parts. Petals glabrous, linear, 1.3-1.4 by 0.2 cm, obtuse, 3-nerved at base, 5-nerved in higher parts. Lip adnate to base of column, deltoid, 0.3 by 0.3 cm, obtuse, 5-nerved, finely papillate on either side of tip only; spur glabrous, clavate, 1.3 cm long, shallowly and broadly grooved above, obtuse.
