Epiphytic on trees or lithophytic on rocks in forests; 1500-2100 m. Hainan, Hong Kong, SE Xizang, NW to S Yunnan [Vietnam].Type specimens from Yunnan ( Simao ).
This species is similar to Eria coronaria ( Lindl. ) Rchb.f., but the lip lobes of the former are discontinuous, and the basal lobes are obviously tall and different. In addition, the individuals of this species are generally tall, and the pseudobulbs are mostly scattered and different from those of Erianthus pedunculatus. It is similar to the labial appendages of some species of Sect Cylindrolobus, and may be more suitable for Sect.Cylindrolobus, as suggested by G. Seidenfaden ( 1982 ). However, the characteristic that the plant becomes black after drying makes it similar to some species in this group. Here we temporarily put it into this group.

Plants glabrous, turning black when dried. Rhizomes creeping, 4-5 mm in diam., with funnel-shaped sheaths 0.7-1.5 cm. Pseudobulbs contiguous or 1-3 cm apart from each other, cylindric, slender, 5-23 cm × 3-6 mm, base with a long, fibrously lacerate sheath. |

Leaves 2, subterminal, sessile, narrowly elliptic, elliptic-lanceolate, oblong-lanceolate, or obovate-elliptic, 10-26 × 2.5-6 cm, with 5-9 main veins, acuminate. |

Inflorescence 1(or 2), arising between leaves, 6-40 cm, up to 12-flowered; floral bracts ovate-lanceolate to linear, 6-11 mm, acuminate. Flowers pure white at first, turning cream-colored and then yellow as they age, scented or unscented; pedicel and ovary 1-1.5 cm. Dorsal sepal narrowly elliptic or oblong-elliptic, 14-16 × 3-5 mm, acute or obtuse; lateral sepals falcate-elliptic or falcate-lanceolate, 12-16 × 5-8 mm, obtuse to acuminate; mentum ca. 5 mm, obtuse. Petals oblong-lanceolate, slightly curved, 11-13 × 1.5-3 mm, acute or obtuse; lip suborbicular or ovate-orbicular in outline, ca. 9 × 8 mm, 3-lobed; lateral lobes parallel to mid-lobe, suboblong or ovate-triangular, obtuse; mid-lobe 2-3 × ca. 2 mm, subtriangular or ovate-triangular, acute; disk with 2 diverging keels and 1 keel on mid-lobe, or with 2 entire lamellate keels below middle and 5 undulate lamellate keels above middle and central 3 of latter extending to mid-lobe, confluent, and reduced to a few teeth. Column ca. 5 mm, foot ca. 5 mm. Fl. Feb-Apr. |
