Fronds remote, up to 10 mm apart, grayish green when dry, papery to herbaceous, subglabrous; stipe dull green to grayish green when dry, not shiny or purple, 20(-25) cm, sparsely scaly to subglabrous; lamina 1-pinnate, narrowly ovate-triangular, 20-30 × 5-10 cm, base truncate, apex acuminate to caudate; rachis grayish green, subglabrous; pinnae 20-30 pairs, sessile to obscurely stalked, trapeziform-falcate, middle pinnae 3.5-7 × 0.8-1.3 cm, dimidiate, apex obtuse to subacute, base asymmetrical, acroscopic side truncate and parallel to rachis, basiscopic side of basal pinnae excavate, in middle pinnae narrowly cuneate and entire, acroscopic margin serrate to crenate, teeth not retuse, pinnae spreading to ascending. Veins distinct, forking and free, ending below a marginal tooth, basiscopic side with (3 or)4(or 5) veins lacking. Sori medial, linear, 3-5 mm; indusia persistent, pale brown, semi-elliptic to linear, membranous, entire, opening toward costa. Plants 20-40 cm tall.
