Leaves patent to erect-patent, oblong, 7-9 by 3-4 cm, apex acute to acuminate, chartaceous. Inflorescences arising laterally from the stem, 2-flowered, spathe laterally compressed. Floral bracts minute, shorter than the ovary, apex acuminate. Ovary 0.6-0.7 cm long, sessile, cylindrical. Flowers c. 2 cm across. Dorsal sepal subspathulate-oblong, 1.3 cm long, apex incurved, broadly obtuse. Lateral sepals obliquely subspathulate-oblong, a little widened at the base, 1.3 cm long, apex incurved, broadly obtuse; mentum short. Petals obliquely subspathulate-obovate, 1.2 cm long, apex incurved, broadly obtuse.
