Plants epiphytic or lithophytic, autotrophic. Pseudobulbs ovoid, bilaterally flattened, 2-6 × 1.5-3 cm, enclosed in leaf bases. Leaves distichous, 5-12, deep green tinged purple at base, lorate, 35-90 × 0.7-1.5 cm, articulate 2.5-6.5 cm from base. Inflorescence arising from within sheaths at base of pseudobulb, suberect or arching, 40-75 cm, slender; rachis 23-29 cm, 3-8-flowered; floral bracts subtriangular, 2-4 mm. Flowers fragrant, 6.5-8 cm in diam.; pedicel and ovary 25-43 mm; sepals and petals green with heavy reddish brown longitudinal stripes and irregular spots of same color, or uniformly greenish yellow; lip pale yellow or white with red-brown venation on lateral lobes and a few red-brown spots and a central longitudinal dash on mid-lobe, or white with yellow venation on lateral lobes and scattered yellow spots on mid-lobe. Sepals narrowly oblong-oblanceolate to narrowly obovate-oblong, 34-52 × 7-14 mm, apex acute to obtuse. Petals falcate, ligulate, 33-53 × 4-7 mm, apex acute; lip elliptic-ovate, 24-43 mm, base fused to basal margins of column for 2-3 mm, 3-lobed; lateral lobes erect, subovate, sometimes shortly ciliate; mid-lobe slightly recurved, cordate to ensiform, 8-9 × 10-11 mm, sometimes sparsely shortly hairy; disk densely hairy at apices of lateral lobes, papillate near base and on mid-lobe, with 2 puberulent lamellae extending to base of mid-lobe; lamellae slightly swollen toward apices. Column 23-32 mm, narrowly winged, sparsely hairy toward base; pollinia 2, subtriangular. Capsule fusiform-ellipsoid, 40-50 × 20-30 mm. Fl. Oct-Jan, fr. Mar-May. 2n = 40, 42.
