Floral bracts ovate-lanceolate, acuminate, much shorter than the ovary. Flowers several not resupinate. Sepals linear-ligulate, acute, 1.3 cm long, glabrous. Median sepal deflexed. Lateral sepals suberect, oblique. Petals subpatent, lanceolate-linear, acuminate, falcate-patent, 0.6 cm long. Lip erect, at the base reniform-concave, strongly contracted; blade elliptic-oblong, concave, acuminate, almost glabrous, 0.9 cm long, near the middle 0.35 cm wide, in the basal half with a high median keel; lip in total 1.3 cm long, when flattened just above the base 0.5 cm wide, in the apical half of the hypochile with a short, rather thick double keel.
