Rhizomes short, erect, apex with sparse dark brown, lanceolate scales. Fronds caespitose; fertile fronds up to 50 cm; stipe dark brown, upward brownish stramineous, 17-20 cm, ca. 2.4 mm in diam., base similarly scaly, upward glabrate; lamina 2-pinnate-pinnatipartite, with pinnatipartite pinnules, oblong, 25-30 × ca. 15 cm, base ± rounded, apex acuminate; pinnae ca. 13 pairs, alternate, ascending, with stalk 4-5 mm, basal pinnae not shortened, broadly lanceolate, up to 10 × ca. 3.5 cm, shortly acuminate at apex, equilateral and rounded at base, pinnate; pinnules ca. 12 pairs, alternate, ascending; basal pinnules shortly stalked (stalk ca. 1 mm), oblong-lanceolate, up to 2 cm × 7-8 mm, base subequilateral, truncate, not auriculate on acroscopic side, cuneate on basiscopic side, pinnatipartite nearly to costule, apex obtuse; pinnule segments 5 or 6 pairs, approximate, oblong; basal acroscopic segments larger, ca. 1 cm × 5 mm, with 3-5 long teeth, obtuse at apex; veins inconspicuous adaxially, visible abaxially, pinnate in segments, lateral veins 3 or 4 pairs, oblique, lower veins forked, upper veins simple. Lamina thinly herbaceous when dried, dark green, glabrate on both surfaces; rachis and costae dark brown, glabrate abaxially, with needlelike spines on adaxial side at base of costa, costule, or midrib. Sori oblong or orbicular, 1 per segment (2-4 in basal acroscopic one), 5 or 6 pairs per pinnule, close to costule; indusia brown, oblong or orbicular, membranous, entire, persistent. Perispore surface without folds.
