Type: Schlechter 20312 (holo B, lost).
Rhizome very short, roots elongated, filiform, flexuose, glabrous. Stems crowded, erect to patent, subflexuose, 30-40 cm long, many-leaved. Leaf sheaths entirely covering the stem. Leaves patent to subpatent, lanceolate-ligulate, 3.5-5.5 by 0.5-0.9 cm, base subpetiolate, apex obtuse. Inflorescences arising laterally from the stem; peduncle hardly developed, 2-flowered, spathe very short, broadly obtuse. Ovary 0.5 cm long, subsessile, cylindrical, glabrous. Flowers c. 2 cm across. Sepals strongly incurved. Dorsal sepal oblong-ligulate, 1.5 cm long, apex obtuse. Lateral sepals falcate, a little widened at the base, 1.5 cm long, apex obtuse; mentum short, obtuse. Petals obliquely linear-spathulate, a little shorter than the sepals, incurved, apex obtuse. Lip 3-lobed in the middle, 0.7 by 0.45 cm, in the basal half with transverse warts, with a linear basal keel extending to the base of the midlobe, on the base of the midlobe with sharp recurved papillae; lateral lobes short, rounded; midlobe much longer, ovate, margins slightly undulate, apex acuminate.
