Plant to 20 cm long. Roots 0.1—0.24 cm diam , finely villose, later becoming almost glabrous. Stem not branched, 30-40 by 0.4—0.7 cm; internodes to 1—3 cm long. Leaves erect-patent, up to 3.0 cm distant; sheaths distinctly recurved, up to 3.0 cm long; blade linear to (oblong-)linear, 15—31 by 2.5—5.2 cm; apex unequally and obtusely bilobed; 9- to 13-nerved; unequally ribbed. Inflorescence 10.3—48.0 cm long, paniculate or racemous, erect to pendent, rather densely 33- to many-flowered, distinctly pubescent; peduncle 7.0—40 cm long, erect, much longer than the terminal rachis; branches up to 8, (sub)pendent, 2.5—16.5 cm long, up to 90-flowered, the basal branches sometimes also branched; terminal rachis 2.0—13 cm long, up to 70-flowered, side-branch rachi 2.0—10 cm long. Floral bracts triangular, 0.1-0.5 cm long; apex acuminate. Pedicel and ovary 0.15—0.25 cm long, minutely pubescent (to subglabrous). Median sepal obovate-oblong to broadly linear, 0.35—0.65 by 0.1.—0.17 cm; apex obtuse to acute, sometimes apiculate; often keeled; 3-nerved. Lateral sepals slightly falcate, obovate-oblong, 0.27—0.45 by 0.13—0.15 cm; apex acute to obtuse, apiculate; 3-nerved (rarely 5-nerved), but veins sometimes obscure. Petals linear to narrowly oblong-ovate, 3.2—6.0 by 0.8—1.1 mm; apex obtuse to acute, 1- or 3-nerved. Lip 3-lobed; midlobe recurved to nearly straight, at a <90° angle to the spur, 0.13—0.18 by 0.13—0.18 cm, broadly ovate to orbicular-ovate, with acute to rounded apex, thickened at base (triangular in longitudinal section); without median callus between the lateral lobes. Lip 3-lobed; lateral lobes erect, almost square, obliquely truncate to triangular, 0.07—0.1 by 0.15—0.17 cm, apex acute; spur 0.35—0.42 by 0.1—0.15 cm, oblongoid, slightly inflated, incurved, with rounded apex, subglabrous to minutely pubescent; back wall tongue oblong, deeply bifid, 0.11—0.17 by 0.05—0.09 cm, attached about half-way down the spur. Column stout, 0.05—0.12 by 0.09 cm; rostellum 0.04—0.05 cm long. Stigma 0.5—0.6 by 0.4—0.5 mm, trapeziform, deeply concave.. Anther 0.01 by 0.08—0.12 cm (including beak). Pollinarium with 4 pollinia; stipe linear, 0.07 by 0.02 cm; viscidium 0.03 cm long; pollinia 4 in 2 pairs, each pair 0.025—0.03 by 0.02—0.025 cm, subspheroid, composed of a smaller body (0.02—0.025 by 0.01—0.015 cm), and a larger body (0.025—0.03 by 0.015 cm).
