Plants large. Stems 30 cm or longer, to 5 cm in diam., stout, many leaved. Leaves recurved, broadly lorate, 40-50 × 5.5-7.5 cm, fleshy, obtuse, unequally bilobed; basal sheaths persistent and amplexicaul. Inflorescences often 1 or 2, to 33 cm; peduncle and rachis 8-10 mm in diam., slightly fleshy, with 2 or 3 broadly ovate-triangular sheaths; raceme nodding, densely many flowered; floral bracts broadly ovate, 5-8 mm, rather fleshy. Flowers fleshy, opening widely, golden yellow, spotted with reddish brown, column white, with 2 purple spots on both apical sides, anther cap pale yellow; pedicel and ovary yellowish green, 1.5-2 cm, stout. Dorsal sepal obovate-oblong, 2.5-3 × ca. 1 cm, obtuse; lateral sepals subelliptic-rhombic, ca. as large as dorsal sepal, abaxially thickened and swollen toward apical midvein. Petals obovate-oblanceolate, smaller than dorsal sepal, obtuse; lip 1.6-1.9 cm, 3-lobed; lateral lobes subobovate, ca. 5 × 3 mm, obtuse; mid-lobe spreading, slightly laterally flattened, long and narrow, ca. 1.3 cm, adaxially with a central longitudinal keel thickened and triangular in basal half, crescent-shaped in apical half. Column ca. 4 mm, stout. Fl. Mar-Apr. 2n = 38.
Epiphytic on tree trunks in open forests or at forest margins; 800-1700 m. S Guangxi, S Yunnan [Laos, Malaysia (Peninsular), Myanmar, Thailand, Vietnam].
