Flowers erect-patent, eventually becoming almost patent. Sepals elliptic-oblong, narrowly obtusely apiculate, glabrous. Median sepal 0.6 cm long. Lateral sepals oblique, 0.7 cm long. Petals weakly decurved, subfalcate, linear-ligulate, obtuse, somewhat dilated towards the apex, glabrous, 0.65 cm long. Lip as long as the petals, deeply 3-lobed, lateral lobes slightly diverging, obliquely subfalcate-oblong, obtuse, 0.4 cm long, mid-lobe oblong, bilobulate to above the middle, lobules obtuse, 0.4 cm long, near the mouth of the spur with 4 calli, in front of these with 3 additional, about equal-sized calli, spur cylindrical-clavate, knee-like bent-porrect, apex weakly retuse, 1 cm long, outside glabrous, inside at the throat densely puberulous. Column towards the apex dilated, laterally at the base puberulous, margins entirely adnate to the lip, 0.45 cm long, auricles obliquely triangular, obtuse. Anther broad, ovate, in front bidentate, with a broadly ovate umbo, glabrous; pollinia obliquely clavate, unequal-sized, viscidium minute, rounded. Ovary with pedicel clavate, minutely puberulous, 1 cm long. (After Schlechter, 1911-1914)
