形态描述：Herbs, perennial, acaulescent, monoecious. Rhizomes elongate creeping, to 2 cm thick, pilose, internodes congested. Stipules triangular, to 1.9 cm long, to 0.9 cm wide, abaxially puberulent, sometimes pilose on midrib, margin entire, apex acuminate, caducous. Leaves fasciculate, alternate; petiole reddish brown, shallowly several grooved, 17-37 cm long, 0.9-1.4 cm thick, whitish pilose and densely puberulent; leaf blade herbaceous, dull, reddish on abaxial surface, dark green with pale green and grayish spots between main veins on adaxial surface, ovate to narrowly so, asymmetric, 24-36 cm long, 13.5-23 cm wide, sparsely pilose along veins on abaxial surface, sparsely setulose on adaxial surface, base oblique, deeply cordate, sometimes slightly overlapping, margin remotely minutely serrulate, somewhat ciliate, apex acute; venation palmate, 7-or 8-nerved. Inflorescences arising directly from rhizome, axillary, cymose, shorter than or as tall as leaves, 15-19.5 cm long, with 6-10 staminate flowers and 3-6 carpellate flowers; peduncle reddish or greenish, 11.5-15 cm long, 3-5 mm thick, glabrous; bracts in pairs, reddish, ovate or broadly so, 2-2.2 cm long, 1.8-2 cm wide, glabrous, margin entire, apex acute to acuminate. Flower buds greenish yellow, sometimes tinged brownish, ovoid; tepals yellow, glabrous. Staminate flowers: pedicel yellowish green, 2.7-4.2 cm long; tepals 4, outer 2 ovate, 1.5-2 cm long, 0.9-1.3 cm wide, apex obtuse, inner 2 narrowly obovate to broadly oblanceolate, 1.7-1.9 cm long, 0.6-1 cm wide, apex obtuse or crenate; androecium actinomorphic, shortly columnar, ca. 8 mm long, ca. 6 mm thick, stamens 80-160, yellow, filaments 2.5-4 mm long, basally fused into a short androphore, anthers fusiform to obovate, 1-4.5 mm long, connective extended, apex acuminate. Carpellate flowers: pedicel greenish, 1.5-2.8 cm long, glabrous; tepals 5, unequal, obovate, apex obtuse or retuse, outer tepals 1.8-2.1 cm long, 1.0-1.1 cm wide, inner tepals narrowly obovate, 1.7-1.8 cm long, 7-8 mm wide, apex retuse or crenate; ovary greenish at anthesis, ellipsoid, unequally 3-winged, glabrous, 2-locular; placentae axile, bilamellate, styles 2, yellow, 2-cleft, 3.5-4.5 mm long, free; stigmas in a strongly spiraled band. Infructescences 42-47 cm long; capsules nodding, unequally 3-winged, abaxial wing ligulate or falcate, 18-22 mm long, 14-16 mm wide, apex obtuse or bluntly truncate, lateral wings much narrower, 6-9 mm long. Seeds numerous, ca. 0.3 mm long, chalazal end rounded, lip of seed nipple-shaped, micropylar end constricted.
