Cymbidium × shangrilaense is a natural hybrid of C. tracyanum and C. gaoligongense , which is similar to the former in floral morphology, but its epidermis has no red-brown spots and stripes, and the column and lip midlobe morphology are different; it is similar to latter in colour but differs in its floral veins and lip morphology.

Epiphytic herbs with ellipsoid-ovoid pseudobulbs, 5.0-11.0 × 2.0-5.0 cm, mostly enclosed in leaf bases. Leaves 5-8, lorate, 56.0-73.0 × 1.4-1.8 cm, articulate 6.0-11.0 cm from base, apex acute. Inflorescence with six flowers arising from axil of leaves, suberect, 36.0-47.0 cm long, with four sheaths. Floral bracts triangular, 4.0-5.0 mm long. Flowers fragrant, 7.0-10.0 cm in diameter; pedicel and ovary 5.5-6.3 cm. Flowers pale yellow, tinged with purplish; sepals and petals with purple-red venation abaxially; lip yellow with pale purple dashes, lamellae deep yellow; column pale purple. Dorsal sepal oblong-elliptic, 6.6-7.4 × 1.6-1.9 cm, apex acute; lateral sepals elliptic, slightly oblique, 5.3-5.8 × 1.0- 1.8 cm. Petals falcate, 6.3-6.7 × 0.8-1.3 cm, apex acute. Lip ovate-elliptic in outline, 3.8-5.2 × 1.5-2.0 cm, base fused to basal margins of column for 5.1-6.1 mm, trilobed; lateral lobes erect, with white hairs on veins; disc with long ciliate, with two lamellae and a row of long hairs between them from base extend to base of midlobe; midlobe elliptic, recurved, sparsely ciliate and with three rows of hairs 2.0-3.0 mm long extending from the base to the apex. Column arcuate, 3.3-4.1 cm long, winged; pollinia 2, ovate, 2.0-3.0 mm.

Etymology:— Named for Shangrila City, Yunnan Province.

Phenology:— Flowering October to December.

Distribution:— Thus far, found only in Shangrila City.

Habitat:— Growing epiphytically.

Parents:— Cymbidium × shangrilaense is considered to be a natural hybrid between C. tracyanum and C. gaoligongense .
