Floral bracts elliptic to oblong-ovate, 2.5-3.1 by 1.2-1.6 cm, apex acuminate, glabrous or glabrescent. Ovary 5.1-8.5 cm long, minutely pubescent to glabrescent. Flowers 4.2-5.5 cm diam. Median sepal oblong, 2.3-2.7 by 1.1-1.4 cm, glabrous, apex obtuse. Lateral sepals obliquely broadly oblong-elliptic, 2.2-2.6 by c. 1.1 cm. Petals obliquely broadly elliptic-oblong, 1.5 cm wide, as long as the sepals. Lip 3-lobed, 1.6-2.1 by 1.2 cm between tips of lateral lobes when flattened; callus shallowly bilobed, erect, oblong, obtuse, 0.33-0.45 cm tall, 03.-0.4 cm wide, with a few apical hairs, lateral at base with glandular hairs; lateral lobes making an angle of 103-127 degrees with the mid-lobe, obliquely oblong-ligulate, 0.63-0.96 long, 0.41-0.55 cm wide at base, 0.21-0.3 cm wide at apex, obtuse; mid-lobe 1.16-1.5 cm long, clawed; claw 0.65-0.95 cm long, 0.8-1.6 mm wide, without knee-like swelling, on either side of the callus with a very short, rounded, sparsely hairy lobule; blade elliptic to almost obcordate, 0.3-0.78 cm wide at broadest part. Column slender, clavate, distinctly curved, 1.66-1.8 cm long, stigma a shallow depression. Anther cucullate, subcordate, slightly umbonate. Fruit subcylindrical, large, glabrescent, 5-6 by 1 cm.
