The plant is about 150cm tall. The rhizome is fleshy, horizontal, and approximately 2cm thick. The tender top is densely covered with dark brown, lanceolate scales, with a diamond-shaped apex and a broadly ovate base, shield-shaped, with fine small teeth along the edges. There are two types of leaves: trophophylls are thick and leathery, brown, broadly ovate, up to 30cm long and about 25cm wide, with a heart-shaped base and no petiole, deeply lobed at the margins; the lobes are elongated triangular, 2-5cm long and 1.5-5cm wide, with a blunt rounded apex, smooth on both sides, and entire margins. The veins are raised on both sides, obliquely ascending in the upper part, spreading in the middle part, and reflexed or arcuate in the lower part, connecting with the transverse veins to form elongated meshes. The sporophylls are thin and leathery, smooth on both sides, elongated, up to 100cm long and about 40cm wide, deeply lobed on both sides of the leaf axis to form narrow wings; the lobes are broadly lanceolate, about 20cm long and 3-4cm wide, gradually tapering at the apex, slightly expanded at the base, with entire margins and cartilaginous edges, slightly oblique upwards. The leaf axis is brown, the midrib is straw-colored, with glands on the lower surface at the base, the lateral veins are distinctly oblique, and the transverse veins between the lateral veins form 5-6 rows of oblique quadrangular large meshes, with many small meshes inside each large mesh. The sporangia are circular to elliptical, arranged in 2 rows between each pair of lateral veins, with 2 in each large mesh, varying in size. Distribution area.
