Herbs perennial, evergreen, rhizomatous, completely glabrous, 15–25 cm tall. Rhizome suberect, subterete, 4–12 mm thick, covered by fibrous bract remains, with many grey roots. Cataphylls 3–4, convolute, as young light green at the base, purple black toward apex, 3.4–6.5 cm long, early splitting into irregular fibres, turning brown when dry. Foliage leaves solitary, on each node of rhizome, very close to each other; petiole stiffly erect, green, 2.3–6.2 cm long; leaf blade dark green, sometimes with small yellow spots, ovate to elliptic, 10–14.2 cm long, 4.0–6.8 cm wide, margin entire, midvein protruding abaxially and sunken adaxially, with 3–4 secondary veins at each sides of the midvein, apex attenuate, base obtuse. Peduncle (specialized reproductive shoot) erect, green with purple-spotted or purple, 3.5–6.4 cm long, with 3–4 ovate bracts, light green with purplespotted, bracts gradually wider from base to top of peduncle, triangular to ovate, 9–12 × 4–8 mm, acute at apex. Flower solitary at top of peduncle. Perigone nontubular, perigone lobes 6–7, lobed to base, ovate to elliptic, 8–11 × 4–6 mm, glabrous, adaxially white at lower 1/3 part of lobes, purple at upper 2/3 part of lobes; abaxially white, purple at margin. Stamens 6–7, opposite to lobes, filaments creamy white, cylindrical, 3–5 mm long; anthers yellow, 3–4 × 2–2.5 mm. Pistil 3.5–4.8 mm high, shorter than stamens, creamy white, style cylindrical, stigma enlarged, 1.7–3.1 mm in diameter, sometimes with 4 inconspicuous radial lines, subcircular or irregularly undulate-lobes at margin.
