Plant perennial, evergreen, herbaceous, rhizomatous, glabrous. Rhizome terete, epigeous to hypogeous, creeping to ascending, branching, 2.5–3.4 cm in diam., densely nodal. Roots grey or greenish, 2–3.3 mm in diam., with dense hairs persistent up to root base. Rhizomes with regularly repeating units, each comprising distichously arranged phylloms: a few cataphylls followed by 3–5 foliage leaves. Cataphylls dull reddish-brown, oblong, 15.5–19.2 cm long, 1.8–2.5 cm wide. Leaves not divided into petiole and lamina. Leaf dark to light green, linear, distally narrowly acuminate, gradually narrowing towards base, 78–105 cm long, 2.1–3.2 cm wide, with finely serrate margin, with prominent midvein on lower surface and 2–3 inconspicuous secondary veins at both sides. Leaf base stiff, erect, adaxially sulcate, 3.7–4.5 mm wide. Peduncle (specialized reproductive shoot) pale green with purple spots, 2.3–4.8 cm long, 1.9–3.1 mm in diam., curved at top so that perigone mouth directed horizontally to the surface, with 3–5 distichously arranged widely ovate acuminate scale purple spotted leaves 8.2–12 mm long, 4–7.2 mm wide. Flowers odorless, solitary at top of peduncle, located at soil level. Perigone completely darkish-burgundy, campanulate, 3.1–3.9 cm long, 2.4–3.6 cm in diam.; tube 12–20 mm long, 7.2–13 mm in diam.; lobes 6, triangular-ovate, slightly acuminate, 11–19 mm long, 3.7–7.2 mm wide, basally with 2 prominent longitudinal keels. Stamens 6, in the same number as perigone lobes, inserted at base of perigone tube, at radii of tepals; filaments basally purple, apically white, cylindrical, short, ca. 1 mm long; anthers subsessile, 2.8–3 mm long, 2.1–2.7 mm wide, introrse. Pistil mushroom-shaped, 7–9 mm long. Style white, cylindrical, 4.4–5 mm long, 3.7–4.2 mm in diam. Stigma darkish-burgundy above, white with purple spots along margin below, shallowly trilobate, up to 1.2 cm in diam., the upper surface convex with projections covered with sharp needle-like outgrowths, shallowly 3-lobed. Ovary inconspicuous, superior, 3-locular. Fruits unknown.
