Rhizome apex with wrinkled light brown broadly lanceolate or ovate scales. Fertile frond up to 85 cm. Stipe light brown or dark brown, up to 30 cm, ca. 3 mm in diam., base with sparse scales same as on rhizome, glabrous upward. Lamina lower part pinnate, upper part pinnatifid, elliptic or narrowly triangular, up to 50 × 30 cm, apical part abruptly acute. Pinnae 3-6 pairs, nearly flat or basal pair slightly inclined, sessile or with indistinct short stalk, usually lanceolate, equally narrow downward or of slightly varying width, up to 16 × 4 cm, base slightly cordate, apex acuminate; basal 1 or 2 pairs often shorter, sometimes nearly as long as upper pinnae, apical pinnae often adnate to rachis. Pinna lobe margin entire or shallowly repand, with few crenate teeth. Main vein obvious on both sides, lateral veins not obvious, or occasionally slightly obvious on lower part, anastomosing with polygonal areoles, distal veins free or connected by inframarginal veinlets. Lamina gray brown when dried, pale abaxially, shiny; rachis and base of costae with sparse brown short multicellular hairs and wormlike or hairlike small scales, costae adaxially with short nodose hairs. Sori variously long, with 1-3 irregular rows of areoles, mostly single, rarely double; indusia broad, brown when mature. Spores semicircular.
