Rhizome apex with broad lanceolate brown scales. Stipe gray, 20-30 cm, base also scaly, sometimes upward with small narrowly lanceolate scales. Fertile frond of young plants deeply pinnatifid; lamina narrowly triangular, base cordate, lower lobes oval-lanceolate or broadly lanceolate, apex shortly acuminate. Fertile frond of adult plants elliptic, up to 45 × 28 cm, with 1 or 2(or 3) pairs of free lower pinnae, apex abruptly narrowed, and pinnatilobate and acuminate, or undulate to entire. Pinnae opposite or subopposite, oblong, subfalcate, base rounded, slightly asymmetrical, sessile or with indistinct stalk, entire, sometimes wavy, apex acuminate. Veins obvious on both sides, anastomosing with polygonal areoles formed by equally thin veinlets. Lamina gray-green when dried, lighter colored on abaxial surface; both sides of rachis and abaxial side of costae with rust-yellow short multicellular hairs and wormlike or coarse hairlike small scales. Sori with variable length, 1-3 irregular rows from costa to lamina margin, sori on acroscopic veinlets double, other sori single; indusia brown when mature, long, narrow. Spore bean-shaped.
