Leaves from several to many (more often), crowded on the top of the stem in large plants. Petioles up to 1.3 m long, nested 1⁄3 - ½ of the length in the vagina. The leaf blade is oval-swept, straight-angled in outline, up to 120 cm long and 50 cm wide, more or less vertical, the edges are slightly or strongly sinuous, monotonously light green on both sides. The lower lobes of the leaf blade are 1/3 - ½ the length of the upper lobe, slightly spherical, often overlapping each other.Inflorescences are paired, growing from the axils of the leaves, equipped with scaly cataphylls. The pedicel barely exceeds the cataphylla during flowering. The bedspread is 13-35 cm long, with a tie at 1⁄6 of the length from the base. The tube was green and ovoid. The plate was covered with a wide-oblong-lanceolate, 10.5-29 cm long, hood-shaped during flowering, later bent, and then dried, scaly, light yellow. The cob is slightly shorter than the blanket, on a short leg. The female flower area is conically cylindrical, 1-2 cm long and 1.5 cm in diameter; the ovary is pale green, about 3 mm in diameter; the stigma is sessile, 3-5-lobed; the blades are conical, yellow. The sterile space is slightly shorter or equal to the female zone, whitish, very slightly narrowed at the point of narrowing of the veil; synandrodia rhombo-hexagonal, about 2.5 mm in diameter, paler below, not fully fused or with a central opening, the upper ones resemble sinandria. Male flower area is cylindrical, about 3-7 cm long, about 2 cm in diameter, whitish; synandria 5-9-staminate, rhombo-hexagonal, convex at the top due to the cap-forming ligaments, about 2 mm in diameter. The appendage is slightly thicker than the male zone at the base, then tapering, making up a significant part of the length of the cob, yellowish.
