Plant herbaceous, perennial, evergreen. Stem constantly erect, to 40–50 cm high, Ø 3–4.5 [3.8] mm, supported by a few prop roots. Stem with regularly repeating units, each comprising 4–6 distichously arranged cataphylls followed by a foliage leaf. Roots grey, Ø 1.5–2.5 [2.1] mm. Cataphylls light grey, oblong, 5–7.6 [6.2] cm long, 4.5–10 [6.2] cm wide, promptly withering. Foliage leaves distinctly divided into petiole and lamina. Petiole green, adaxially sulcate, 5.5–11 [8.8] cm long, Ø 2.0–2.5 [2.3] mm. Lamina green, elliptic, basally cuneate and apically acuminate, 10–19 [13.7] cm long, 2–6 [3.5] cm wide, with midvein somewhat prominent at abaxial surface. Peduncle (specialized reproductive shoot) whitish green, 4.5–5.5 [5] mm long, Ø 1–1.7 [1.4] mm, with 4–5 whitish, widely ovate, acuminate, 7 mm long, 5 mm wide distichously arranged scale leaves. Flower solitary at top of peduncle, upright. Perigone 6.5–10 [8.1] mm long, Ø 6.7–8.4 [7.6] mm; tube whitish green, smooth and lustrous (later becoming greyishbrown and slightly longitudinally rugose) outside, purple inside, globoid, 5.5–9 [7.1] mm long; lobes 6 (rarely 4), whitish green and smooth outside, purple and papillose inside, triangular, very small, ca. 1 mm long, 1.3–2 [1.6] mm wide, upright or slightly curved outward, leaving orifice ca. 1.5 mm wide. Stamens 6 (rarely 4—in the same number as perigone lobes), inserted at middle level of perigone tube below upper surface of stigma, at the same radii with tepals; anthers sessile, 1.5–2 mm long, 1 mm wide, introrse. Pistil clubshaped, 4.1–5 [4.5] mm high. Style white, cylindrical, 1–1.5 mm long, Ø 1–1.5 mm. Stigma purple, widely obconical, 2.6–3 [2.8] mm high, Ø 5–6 [5.5] mm at top, with 6 very prominent longitudinal ridges which alternate with stamens and 6 less prominent longitudinal ridges opposite stamens; upper surface flat, star-shaped with 6 large and 6 small rays which correspond to ridges. Larger ridges of stigma touch inner surface of perigone tube and divide inner space of flower into 6 chambers, with one stamen in each. Ovary inconspicuous, superior, 3-locular. Fruits green, subspherical, 11–13 [12] mm long, Ø 9.5–13 [11.8] mm, 3-seeded, slightly tuberculate; carpophore absent.
