Type: Schlechter 20185 (holo B, lost).
Rhizome very short, roots elongated, filiform, flexuose, glabrous. Stems crowded, patent, slender, flexuose, 60-80 cm long, leaved many-leaved. Leaf sheaths entirely covering the stem. Leaves patent to erect-patent, lanceolate-ligulate, 5.5-10 by 1-1.7 cm, apex subacute. Inflorescences arising laterally from the stem, peduncle hardly developed, 2-flowered, spathe short, laterally compressed, obtuse. Ovary 0.7 cm long, subsessile, cylindrical, glabrous. Flowers c. 2.5 cm across. Sepals incurved, verruculose outside. Dorsal sepal oblong-ligulate, 1.8 cm long, apex obtuse. Lateral sepals obliquely oblong-ligulate, a little widened at the base, 1.8 cm long, apex obtuse; mentum short, obtuse. Petals obliquely oblanceolate-spathulate, a little shorter than the sepals, outside verruculose, apex obtuse. Lip 3-lobed in the middle, 0.75 by 0.5 cm, inside transversely rugulose, with a linear basal keel extending to the base of the midlobe, on the base of the midlobe sparsely warty; lateral lobes short, triangular, obtuse; midlobe broadly elliptic, margins lightly undulate, apex apiculate. Column short, rather thick, clinandrium 3-lobulate, the lateral lobules rounded, the median small, tooth-like; column-foot incurved, at the apex with a 3-lobulate cavity.
