Fertile frond up to 70 cm, ca. 8 mm in diam.; stipe brown at base, scaly; scales fewer but similar to those on rhizome; stipe upward stramineous, deeply grooved adaxially; lamina 2-pinnate with pinnules pinnatipartite, deltoid, up to 70 × 60 cm, apex acuminate; pinnae up to 8 pairs, alternate, ascending, with stalk up to 4 cm, base brown, upward stramineous, basal pinnae largest, broadly lanceolate, up to 40 × 17 cm, slightly narrow to base, base truncate, apex acuminate; pinnules up to 15 pairs, alternate, slightly ascending, with stalk up to 4 mm, lanceolate, up to 9 × 2 cm, base asymmetrical, cordate, pinnatipartite, apex caudate-acuminate; pinnule lobes up to 12 pairs, spreading, deltoid or sickle-shaped lanceolate, ca. 1 cm × 4 mm, apex slightly narrowed, acuminate or subrounded; basal basiscopic lobe markedly larger, dentate at margin, basal 1 or 2 pairs of pinnule lobes nearly free, upper pinnule lobes connate with narrow wings; veins not prominent on adaxial side, visible abaxially, pinnate, veinlets 8 pairs per pinnule lobe, mostly forked, ascending. Lamina light brown, submembranous when dry, costules abaxially with sparse light brown glands; rachis and costa stramineous, shallowly grooved adaxially. Sori linear, up to 3 mm, 6 pairs per pinnule lobe, from costule upward to 2/3 of veinlet length, single or double on basal acroscopic veinlets; indusia light brown, linear, thinly membranous, persistent. Spores reniform, perispore with densely aculeate ornamentation.
