Plants glabrous, turning black when dried. Rhizome creeping, 4-5 mm in diam., often with funnel-shaped sheaths 6-7 mm. Pseudobulbs contiguous or 1-2 cm apart from each other, cylindric, 5-15 cm × 3-6 mm. Leaves 2, subterminal, sessile, narrowly elliptic or obovate-elliptic, rarely ovate-lanceolate, 6-16 × 1-4 cm, acute or obtuse. Inflorescence arising between leaves, 10-30 cm, 2-6-flowered; floral bracts lanceolate or linear, rarely ovate-lanceolate, 5-8 mm. Flowers white, with purple stripes on lip; pedicel and ovary ca. 1.5 cm. Dorsal sepal elliptic-lanceolate, ca. 17 × 5 mm, obtuse; lateral sepals falcate-lanceolate, ca. 15 × 5 mm, obtuse; mentum conspicuous. Petals oblong-lanceolate, ca. 17 × 4.5 mm, obtuse; lip oblong in outline, 14-15 × 11-12 mm, 3-lobed; lateral lobes divaricate, suborbicular or suboblong; mid-lobe triangular or subsquare, ca. 5 × 4 mm, acute or subtruncate; disk with 3 entire or undulate lamellae running from base to mid-lobe and with 2-4 additional crenate or undulate lamellae on mid-lobe. Column ca. 5 mm, foot ca. 5 mm. Capsule obovoid-cylindric, ca. 2 cm; fruiting pedicel ca. 3 mm. Fl. May-Jun. 2n = 34, 36, 38, 44, 52.
Epiphytic on tree trunks or lithophytic on rocks in forests; 1300-2100 m. Guangxi, Hainan, SE Xizang, NW and S Yunnan [Bhutan, India, Nepal, Thailand, Vietnam].
Eria medogensis, described from SE Xizang, represents a peloric form of E. coronaria in which the lip is undifferentiated and resembles the sepals and petals.
