Three-Calli Coelogyne is a miniature sized, rock-dwelling or tree-dwelling orchid with caespitose, ellipsoid-obovoid pseudobulbs carrying 2, elliptic-lanceshaped, lanceshaped or linear, pleated, 3 veined, stalked base leaves. The plant blooms in the spring through fall on a short, single flowered inflorescence enveloped by overlapping sheaths and has scarious, brown floral bracts all arising on a newly emerging growth. Flowers are pale yellow or greenish, 2-2.5 cm in across, lip with 3 small spots at base, calli on disk orange, column pale yellow; flower-stalk and ovary about 1 cm. Sepals are narrowly ovate, oblong-ovate, or broadly lanceshaped, 12-19 x about 5 mm, dorsally carinate, 5-veined, tapering; lateral sepals slightly oblique. Petals are ovate-oblong or nearly broadly lanceshaped, 13-18 x about 4 mm, 3-veined, pointed to tapering. Lip is obovate-oblong to spoon-shaped, 10-20 x 6-7 mm, sigmoid at base, entire, inprominently wavy, flat, apiculate, or subrounded; disk with 2 or 3 short longitudinal lamellae. Three-Calli Coelogyne is found in Nepal, Bhutan, NE India, Laos, Thailand, Vietnam, and China, at altitudes below 2100 m. Flowering: December.
