Plants summer-green. Rhizome slender, creeping, deep below soil surface, ca. 2.5 mm in diam., apex with brown, lanceolate, membranous scales; fronds sparsely arranged. Fertile frond up to 80 cm; stipe stramineous, 25-40 cm, densely scaly along entire length with pale brown, linear to lanceolate membranous translucent scales and nodose soft hairs up to 3 mm, scales on upper part narrow; lamina ovate, narrowly elliptic, or narrowly subdeltoid, 18-40 ×10-25 cm, base slightly narrowed or not, apex abruptly narrowed; free pinnae 7-12 pairs, spreading or slightly ascending, narrowly elliptic or linear-lanceolate, 3.5-15 × 1-3.5 cm, base broadly cuneate or subtruncate, rarely shallowly cordate, sessile or lower pinnae shortly stalked, apex acuminate or shortly acuminate; upper pinnae adnate, pinnatipartite up to or near costa; pinna lobes up to 18 pairs, slightly oblique or spreading, oblong or slightly obliquely ligulate-oblong, entire, repand, or shallowly crenate at apex, apex truncate or rounded, sometimes slightly impressed; veins pinnate with less than 7 pairs of veinlets, simple or forked. Lamina herbaceous, brown-green when dry, darker on adaxial surface; rachis hairy along entire length with dense, pale brown, hyaline, often shrunken, soft, nodose hairs 2-3 mm, lower part of rachis hairy and scaly with 2-or 3-cells-wide, linear, hyaline scales, abaxial side of costae and both sides of veinlets with nodose hairs, lamina between veinlets with ± gray-white nodose hairs. Sori shortly linear, straight or slightly curved, 1-6 pairs per lobe, mostly single, subcostular, double on basal acroscopic veinlets; indusia yellow-brown when mature, membranous, with short nodose hairs, margin lacerate, flat when young.
