Growth form Epiphyte, part seen 43 cm high. Rhizome not seen. Roots filiform, long, flexible, glabrous. Stem long, laxly branched, laterally compressed, in cross section elliptic, proliferously leafed, completely covered by leaf sheath, internodes 3 cm long, 0.23 cm wide, smaller upwards. Leaf linear, erect-patent, coriaceous, narrowed towards apex, midrib when dried grooved above, obtusely prominent below; apex unequally 2-lobed, shorter acute, longer obtuse, 0.3-0.6 cm long; base narrowed, half-clasping the stem; lamina 6.5-8.25 cm long, 0.5 cm wide; sheath tubular, warty in apical part, basal part glabrous; apex toothed, with glabrous margin. Inflorescences terminal, 9-flowered, reflexed, subracemose, when young enveloped by a spathe. Spathe tubular, right, orbicular-ovate, acuminate, acute, basal part strongly concave, 11-nerved, 1.1 cm long, 0.85 cm wide; floral bracts  oblong-subelliptic, acuminate, acutely mucronate, dorsally near the apex, concave, 3-nerved, membranous, 0.57 cm long, 0.27 cm wide. Flowers upright, glabrous, 0.7 cm long. Median sepal shortly adnate to the lateral sepals, elliptic, obtuse, 3-nerved, 0.48 cm long, 0.3 cm wide. Lateral sepals shortly fused, clasping the spur, obliquely ovate, obtuse, dorsally near the apex with conical apiculum, 3-nerved, free part 0.46 cm long, in total 0.56 cm long, 0.36-0.38 cm wide; mentum saccate, subglobose, 0.2 cm long. Petal obliquely subrhombic, obtuse, 3-nerved, 0.44 cm long, 0.24 cm wide. Lip shortly adnate to the column, to the apex of ovary 0.3 cm long, including spur 0.48 cm long, concave, convex, 7-nerved, when flattened nearly semiorbicular, 0.2 cm long, 0.3 cm wide; epichile recurved margin; hypochile abruptly transversely thickened, spurred; spur making an acute angle with ovary, obliquely oblong, obtuse, 0.3 cm long. Column slightly incurved, dorsally convex, including anther 0.16 cm long, apex broadly trapezium-shaped, broadly obtuse, retuse; clinandrium concave, almost entire; stelidia triangular, subacute. Anther making straight angle with column, cucullate, 0.12 cm wide, transversely elliptic, apex truncate-rounded, not recurved, margin membranous, connective at base conical-raised, basal part channelled; rostellum broad, crescent-shaped, broadly retuse; stigma transverse, crescent-shaped, with lower margin strongly elongated, incurved; pollinia not seen; viscidium not seen. Ovary cylindrical, curved, 0.54 cm long,  3-grooved. Capsule not seen.
