Type: Schlechter 16887 (holo B, lost).
Rhizome very short, roots elongated, filiform, flexuose, glabrous. Stems crowded, erect, laterally compressed, unbranched, 40 cm by 4-6 mm, many-leaved. Leaf sheaths entirely covering the stem, densely verruculose. Leaves erect-patent, oblong-ligulate, 8-9 by 1.4-2.3 cm, apex obtuse. Inflorescences arising laterally from the stem, subsessile, 2-flowered, spathe oblong, laterally compressed, obtuse, covered by a large auricle of the leaf-sheaths. Pedicel and ovary 1 cm long, verruculose. Flowers c. 4 cm across. Sepals outside verruculose-papillose. Dorsal sepal lanceolate, 2.5 cm long, apex obtuse. Lateral sepals strongly falcate, a little widened at the base, 2.5 cm long, apex obtuse; mentum short, obtuse. Petals linear-falcate, a little shorter than the sepals, apex obtuse. Lip oblong, 1 by 0.65 cm, in basal half sparsely pubescent, with a linear basal keel extending to the middle, in apical half with many clavate, flexuose papillae, apex apiculate. Column short, rather thick, clinandrium 3-lobulate, the lateral lobules rounded, the median minute, tooth-like; column-foot concave, near the apex with an elliptic cavity. Anther cucullate, glabrous.
