Plants 1.3-2.2 m tall. Rhizomes thick and short, erect. Fronds clustered; stipes 70-120 cm, bases brown, with deep brown triangular-lanceolate shortly hairy scales and glaucous short acicular hairs, distally dark stramineous, distally with grayish white hooked long hairs, rachises similarly hairy; laminae narrowly oblong, 60-100 cm or more, 25-40 cm wide, bases not tapering, pinnate-pinnatifid, apices acuminate and pinnatifid; pinnae 25-30 pairs, distal ones alternate, proximal ones subopposite, spreading, linear-lanceolate, 15-20 × 3-3.5 cm, broadly cuneate at bases, pinnatifid nearly to costae, caudate-acuminate at apices; segments ca. 23 pairs, spreading, middle ones oblong-lanceolate, 11-14 mm (proximal 1 or 2 pairs slightly shortened), 5-6 mm wide, entire, rounded-obtuse at apices. Veinlets evident abaxially, simple, 10-15 pairs per segment, proximal pair arising from slightly higher above base of costules and all reaching margins above sinuses. Laminae papery, brownish green when dry, subglabrous on both surfaces or with sparse short acicular hairs abaxially, rachises grooved adaxially, with dense hooked long hairs on both sides, abaxially with occasional small brown lanceolate scales, pinna bases abaxially with brown linear-lanceolate aerophores. Sori orbicular, smaller, attached below middle of veinlets and close to costules, 7-12 pairs per segment; sporangia glabrous.
