Rhizomes erect or ascending, clothed with brown-red, membranous, broadly lanceolate large scales at apex. Fronds caespitose; fertile fronds (30-)100-120 cm; stipe stramineous or slightly reddish brown, (6-)24 cm, base with brown, ovate-lanceolate scales, upper part with thin scales or tortuous, hyaline, multicellular hairs; lamina pinnate-pinnatipartite, narrowly oblong-lanceolate or narrowly oblanceolate, (25-)80 × (10-) 15(-25) cm, gradually narrowed to base, apex pinnatifid-shortly acuminate; pinnae (10-)30 pairs or more, lower pinnae subopposite, upper pinnae alternate, spreading or slightly ascending, ca. 2 cm apart, 7 or 8 pairs of lower pinnae gradually shortened; basal pinnae 1-2 cm, broadened, triangular; middle pinnae lanceolate to narrowly lanceolate, (4-)8-10(-13) × 1-2 cm, broader at base, base subtruncate or broadly cuneate, pinnatipartite, apex acuminate; pinna segments (10-)15(-20) pairs, separated by narrow space, slightly ascending, oblong or deltoid-oblong, (3-)8-9(-12) × 3-5 mm, adnate to broad wing of costa, margin toothed or subentire, apex obtuse or obtuse-rounded. Veins visible on both surfaces, pinnate in segments, 4 or 5(-7) pairs, simple, sometimes forked in basal segments. Lamina herbaceous when dried, brown-green, rachis, costae, and veins on both surfaces with sparse longer multicellular hairs. Sori oblong or shortly linear, sometimes J-shaped in distal part of pinna, 1.5-2 mm, 3-5 pairs per segment; indusia similar to sori, brownish, slightly erose at margin, persistent. Spores bilateral, perispore surface with rugate, rugate-saccate, or papillate processes. 2n = 160*.
