Terrestrial. Rhizome creeping, branched, rooting, initially covered with large, overlapping, obtuse, shining, wide, c. 1-1.4. cm long sheaths. Pseudobulbs 0.6-2 cm apart; base adnate to the rhizome, curved-ascending, when dried 0.9-1.6 cm long; 1-leaved. Leaf oblong to lanceolate-elliptic, fleshy-coriaceous, when dried rigid, c. 1.7-2.5 by 0.6-0.5 cm; base contracted in a petiole and conduplicate; apex conduplicate, obtuse; midrib when dried dorsally prominent. Inflorescences 1-flowered, from the rhizome, ascending; peduncle elongated, robust, terete, c. 12-20 by 0.08 cm, with 2 distant, small, tubular, obtuse, sheaths close together. Floral bract tubular, keeled, laterally compressed-apiculate, 0.55 cm long. Flower medium size, rather fleshy, c. 1.5 cm long, the sepals subparallel. Median sepal oblong-elliptic, slightly concave, 5-nerved, c. 1.35 by 0.6 cm; apex with incurved margins, obtuse, apiculate; margins finely ciliate. Lateral sepals decurrent on the column-foot, obliquely oblong, 7-nerved, c. 1.5 by 0.8 cm; apex narrowed, hardly contracted, subobtuse, concave; posterior margins narrowly incurved, only at the base with cellular margin; front margin swollen, bent inwards, papillose-finely ciliate. Petals very small, porrect, strongly oblique, 1-nerved, dorsally strongly keeled, in total 0.77 cm long; claw short, 0.15 by 0.47 cm; blade when flattened short obliquely rhombic; middle part concave, front margin strongly obtusely angled, dilated; apex recurved, then slightly incurved, acuminate-acute. Lip inserted on the column-foot, immobile, porrect, boat-shaped, parallel to the column, from above oblong-elliptic, with 3 lobules, 5-nerved, outer nerves near the margins close together, in total c. 1.25 by almost 0.5 cm; claw short, fleshy, at the apex with lateral, fleshy, laterally compressed, erect, obliquely oblong, falcate-recurved, obtuse, 0.24. cm long lobes; front margins decurrent along veins close to the midrib, posterior margins of the claw behind the lateral lobes with a fleshy, pointing backwards transverse low callus; towards the apex narrowed, apex rounded, margins of the sac thickened; mid-lobe apically slightly recurved, from above in outline suborbicular, convex, with 2 longitudinal grooves, at the base channelled, underneath concave except for the thick margins, 0.2 cm wide; lip underneath convex, slightly channeled. Column 0.37 cm long; clinandrium hollow, strongly obliquely crescent-shaped; stelidia elongated, much longer than the anther, at the base dilated, filiform-subulate, slightly sigmoid. Anther cucullate, oblong, quadrangular, 0.13 cm long; apex slightly recurved, truncate, cellular; connective oblong-thickened; stigma longitudinal, oblong; column-foot making an obtuse angle with the ovary, slightly incurved, the apex free from the lateral sepals, somewhat incurved, very thick, semiorbicular in cross-section. Ovary obliquely obconical, 6-grooved, 0.5 cm long; pedicel terete, c. 1.1 cm long, 0.26 cm above the base articulate. (After Smith, 1929)
