Lateral sepals patent, more or less subfalcate, 0.6 by 0.15 cm. Petals rather broadly subfalcate, slightly longer than the median sepal, 0.25 cm wide, forming a helmet with the median sepal, at the base on the posterior margin with a very short lobule. Lip 3-lobed just above the cuneate or semicircular base, c. 0.8 cm long, spurred; lateral lobes very narrowly triangular, 0.6 cm long, long acuminate; mid-lobe narrowly triangular, slightly shorter than the lateral lobes, acute; spur pointing backwards, straight or incurved, narrowed in the middle, widest at the mouth.
