Shoot erect, stout, unbraned, 6–10(12) cm tall, 1–2 cm in diameter, densely nodal, with many thick, rigid, spirally arranged, semi-woody, straight to slightly curved prop roots, 5–12 cm long before entering the soil and then freely branching. Cataphylls convolute, linear to lanceolate, as young greenish–brown, later becoming gray to light gray–brown, papyraceous, to 30 cm long, early splitting into fi brous remains. Leaves densely crowded, petiolate. Petiole stiff, erect, straight, (20)25–40(45) cm long, (3)4–7(8) mm in diameter. Leaf blade erect to arching, narrowly elliptic to lanceolate, attenuate at base and at apex, (45)50–60(70) cm long, 2–6(7) cm wide, straight to slightly wavy along margin, uniform green above and below, with prominent midvein on lower surface and insignifi cant, secondary veins. Flowers solitary, arising from the apical part of the shoot, pedunculate. Peduncle arising horizontally, dark green, indistinctly marked with dirty purple–brown marks, (3)4–6(8) cm long, 2–4(5) mm in diameter, with 2(3) sterile bracts at base; bracts ovate to broadly ovate, coriaceous, obtuse, 5–8 mm long, 0.3–0.6 mm wide. Floral bracts 3, broadly triangularovate, concave, (0.6)1.0–1.8(2.0) cm long, 0.5–0.8(1.0) cm wide, densely adpressed to perigone from below. Perigone shortly obpyramidal, container-like, verruculose outside, fi nely rough inside, down faced, 3–4 cm in diameter, 1–2 cm long, with 6 incurved half-united lobes forming a star-like perianth opening, 1.5–1.8 cm in diameter. Lobes subequal, broadly triangular, fl at, straight or apically adaxially curved, with slightly revolute scarious margin, blunt to roundish at apex, 2–3 mm long, 7–9(10) mm wide at base. Stamens 6, sessile, inserted at basal, urceolate part of perigone; anthers ellipsoid, 4–5 mm long, 1.2 mm wide; pollen sacs introrse; pollen whitish. Pistil desk-shaped, peltate; ovary inconspicuous, cylindrical; style stout, cylindrical to clavate, 6–7(8) mm tall, 4–5 mm in diameter; stigma fl eshy, entire, discoidpeltate, (0.8)1.0(1.2) cm in diameter, with numerous, dense, radial, irregularly denticulate ridges, forming at center a deep cavity.
