Monochilus affinis Lindley, Gen. Sp. Orchid. Pl. 487. 1840; Adenostylis arisanensis (Hayata) Hayata; Zeuxine arisanensis Hayata; Z. sutepensis Rolfe ex Downie; Z. taiwaniana S. S. Ying; Z. uraiensis S. S. Ying.
Plants 11-30 cm tall, slender. Rhizome elongate. Stem erect, deep reddish brown to greenish brown, 4-6-leaved. Leaves subrosulate, withered and pendulous at anthesis, often reddish, ovate, ovate-lanceolate, or elliptic, 2.5-4 × 1.2-2.5 cm, apex acute or obtuse; petiole-like base ca. 1 cm including tubular sheath. Inflorescence 5-20 cm, with 1 or 2 puberulent sterile bracts, pubescent, pale brown; rachis 3-9 cm, subdensely several to many flowered; floral bracts ovate-lanceolate, 7-8 mm, pubescent on margin and lower half of abaxial surface, apex long acuminate. Flowers resupinate or occasionally erect, small; ovary and pedicel fusiform, 5-6 mm, glabrous to puberulent. Sepals not spreading, dark brownish green at base, white toward apex, pubescent; dorsal sepal broadly ovate, 4-5 × ca. 2.5 mm, concave, 1-veined, apex obtuse or acute; lateral sepals ovate-oblong, slightly oblique, 3.5-4.5 × ca. 2.5 mm, 1-veined, apex obtuse. Petals white, elliptic to obovate, oblique, ca. as long as dorsal sepal, 1.5-2 mm wide, 1-veined, apex obtuse; lip white or pale yellow, Y-shaped, 4.5-6 mm, 3-partite; hypochile concave-saccate, containing 2 subulate, hooked calli; mesochile short, to 1 mm, tapering toward apex, margin involute; epichile dilated, 2-lobed; lobes not diverging widely, obovate-flabellate, widening toward apex, 2-2.5 × 2-2.2 mm. Column 1.5-2 mm; wings triangular; anther ovoid-lanceolate, to 2 mm; rostellum arms oblong, ca. 0.6 mm. Fl. Feb-Apr. 2n = 20.
Shaded places in forests, forest margins, valleys; 800-1700 m. Guangdong, Hainan, Hunan, Taiwan, Yunnan [Bangladesh, Bhutan, India, Laos, Malaysia, Myanmar, Thailand, Vietnam].
Hong Kong plants previously treated as Zeuxine gracilis (Breda) Blume (e.g., by S. Y. Hu, Gen. Orchidaceae Hong Kong, 50. 1977) are probably referable here.
