Plants terrestrial, autotrophic. Pseudobulbs ovoid, small, 0.8-1.2 × 0.7-1 cm, with thick roots at base. Leaves 3-5, subterminal, lorate, 23-38(-70) × 0.5-0.7 cm, often slightly conduplicate, with translucent veins, not articulate at base, margin usually serrate, apex acuminate. Inflorescence arising from base of pseudobulb, erect, usually 20-30 cm; peduncle with 5 or 6 sheaths; sheaths to 7 cm, with purple-red venation; rachis 1- or very rarely 2-flowered; floral bracts 40-50 mm, much longer than ovary. Flowers not scented, thickly textured; pedicel and ovary 30-35 mm, usually pale purple-red; sepals and petals green, with a purple-red midvein and finer lateral venation; lip white with purple-red markings; column greenish, with minute purple-red spots and striations, tinged purple-red at apex. Sepals narrowly oblong-ovate or suboblong, 36-38 × 11-13 mm, apical margin often incurved, apex subacute. Petals spreading forward and loosely clasping column, suboblong, 20-28 × 9-13 mm, apex obtuse; lip ovate, 20-25 mm, not fused to basal margins of column, 3-lobed; lateral lobes erect; mid-lobe recurved, oblong-ovate, 10-14 × 8-10 mm, apex obtuse; disk with 2 lamellae extending from near base of lip almost to base of mid-lobe; lamellae convergent at their apices and forming a short tube. Column 12-18 mm, narrowly winged. Fl. Feb-Mar.
● Rocky places, open forests or well-drained and grassy slopes; 1000-3000 m. Guizhou, Hubei, Sichuan, Taiwan, Yunnan.
This species can be distinguished easily from Cymbidium goeringii by its narrow and non-articulate leaves, its much longer inflorescence, and its thickly textured and unscented flower with green sepals and petals.
