Herbaceous, perennial, rhizomatous, evergreen plant. Rhizome creeping, epigeous, 4.6–8.7 mm in diameter. Roots grey 2.1–2.5 mm in diameter. Rhizomes with regularly repeating units with very short internodes, each comprised of a few distichously arranged cataphylls followed by a foliage leaf. Cataphylls oblong, 4.2–7.7 cm long, 9–11 mm wide, promptly withering and disintegrating. Foliage leaves distinctly divided into petiole and lamina. Petiole light green, adaxially sulcate, 12.0–41.5 cm long, 1.5–3.5 mm in diameter. Lamina light green, oblong, basally cuneate and distally acuminate, 15.0–31.5 cm long, 4.3–6.4 cm wide, with 3–4 secondary veins at both sides of the midvein. The midvein and the secondary veins somewhat prominent at lower surface. Peduncle purple, 0.9–1.6 cm long, 2.5–4.0 mm in diameter, with 3–7 purple, widely ovate, 7.3–7.4 mm long, 7–8 mm wide, distichously arranged scale leaves. Peduncle curved at top so that flowers become nutant (directed downward). Flowers solitary at the end of peduncle. Perigone completely purple to reddish purple, 13.5–13.6 mm long, 12.6–14.9 mm in diameter; tube bowl shaped to widely campanulate, 5.9–6.6 mm long, in diameter the same as the whole perigone; lobes 6, erect to incurved, oblong, widely elliptic, obtuse (rounded at the top), 6.6–7.8 mm long, 4.9–6.8 mm wide. Stamens 6 (the same number as the perigone lobes), subsessile, inserted at the bottom of the perigone tube lower than stigma, at the radii of tepals; anthers 2.2–2.5 mm long, 3.0–3.2 mm wide, introrse, their connectives white, ca 1 mm in diameter. Pistil abruptly widely obconic, 3.8–5.1 mm high. Style white with purple spots, obconic, 1.5–3.0 mm long. Stigma white with purple spots (mostly along margin) at lower and upper surfaces, round, smooth, 8–12 mm in diameter. Ovary inconspicuous, superior, 3-locular. Fruits purplish black, globoid, 10–15 mm in diameter, with conical protuberances up to 3.8 mm long. Fruits sometime with carpophore 10–16 mm long, 3.7 mm in diameter.
