Plants 9–25 cm. Pseudobulbs ovoid, 20 ×10 mm, sheathed by bracts and persistent leaf-bases, previous year’s pseudobulb usually present, connected by short rhizome. Stems bright green, with or without purplish brown tinge, angled, sometimes obscurely winged or fluted distally. Leaves 2; blade conduplicate, dark green, glossy, ovate-elliptic, keeled abaxially, 4–18 × 2–8.5 cm, succulent, apex obtuse to acute. Inflorescences 4–15 cm; floral bracts subulate, 2 × 1 mm, apex acute; pedicels slender, 5–7 mm. Flowers 5–31, mauve-purple and green; dorsal sepal oblong-lanceolate to narrowly lanceolate, 8–11.5 × 1.2–2 mm, apex obtuse to acute; lateral sepals oblong-lanceolate to narrowly lanceolate, 8–11.5 × 1.2–2 mm, apex obtuse to acute; petals pendent, curved, tubular, narrowly linear to filiform, 8.5–12 × 0.2–0.3 mm, margins strongly revolute; lip translucent, mauve to pale-purple or rarely green with prominent purplish veining, cuneate-obovate to suborbiculate, 8–12 × 6–10 mm, base slightly auriculate, apical margin erose-serrulate, apex subtruncate, mucronate; column winged apically, 3–4 × 1–1.5 mm, with 2 blunt tubercles on inner surface near base; anthers yellow; pollinia yellow. Capsules: pedicel 11–18 mm; body ellipsoid, 15 × 5 mm, veins often slightly winged.
Phenology: Flowering May–Jul (north).
Habitat: Mature mesic to moist deciduous forests, pine woods, rich moist humus, often colonizing previously open, disturbed habitats during early and middle stages of reforestation
Elevation: 10–1500 m

Discussion
Liparis liliifolia has what appear to be extremely similar relatives in Japan [L. japonica (Miquel) Maximowicz and L. makinoana Schlechter] and China (L. pauliana Handel-Mazzetti and L. cathcartii Hooker f.). Further work is needed to clarify the relationships among these five species. It could be a case of either divergent evolution from a common ancestor or convergent evolution from two or more ancestors.
