Oreorchis fargesii var. subcapitata Hayata; O. intermedia S. S. Chien; O. ohwii Fukuyama; O. subcapitata (Hayata) Schlechter.
Plants 18-30 cm tall. Pseudobulbs ellipsoid to subglobose, 1-2.5 × 1-2 cm, 2- or 3-noded, usually persisting and forming a tight chain of pseudobulbs connected by a short rhizome. Leaves 2, linear-lanceolate or linear, plicate, 15-28 × 0.8-2.5 cm, gradually tapering at base, apex acuminate; petiole-like stalk articulate, 3-5 cm, usually enclosed in tubular sheaths and forming a pseudostem. Inflorescence 18-30 cm, with 2 or 3 tubular sheaths below middle; rachis 2-6 cm, densely more than 10-flowered; floral bracts ovate-lanceolate, 3-5 mm. Flowers white, with brown lamellate crests on lip and pale brown spots on mid-lobe of lip; pedicel and ovary 7-12 mm. Sepals oblong-lanceolate, 9-11 × 2.5-4 mm, apex acuminate; lateral sepals oblique, slightly wider than dorsal sepal. Petals narrowly ovate to ovate-lanceolate, 9-10 × 3-3.5 mm, apex acuminate; lip oblong-obovate, 7.5-9 × 4-4.5 mm, 3-lobed near base, shortly clawed at base; claw ca. 1 mm; lateral lobes linear, 2-3 × ca. 0.7 mm, margin minutely ciliate, apex obtuse; mid-lobe subelliptic-obovate or rhombic-obovate, ca. 6 × 4 mm, basal margin often ciliate, apical margin crisped, apex obtuse-rounded and irregularly incised; disk with a short lamellate, longitudinally channeled callus between lateral lobes. Column ca. 3 mm, base thickened. Capsule narrowly ellipsoid, ca. 20 × 8 mm. Fl. May-Jun, fr. Sep-Oct.
