Fertile fronds up to 35 cm; stipe green-stramineous, 2-8(-15) cm, upward glabrous, deeply grooved adaxially; lamina 1-pinnate, oblong-lanceolate, 8-15(-20) × 3-6 cm, slightly narrowed to base, apex pinnatilobate and acuminate; pinnae 8-24 pairs, alternate or lower pinnae opposite, subspreading, lanceolate, base asymmetrical, basiscopically cuneate, acroscopically auricles parallel to rachis, with stalk up to 2 mm, margin (especially acroscopically) repand with shallow rounded lobes, lobes thinly serrate, apex acute; veins pinnate, slightly raised on abaxial surface, veinlets 2 or 3 pairs in basal auricle, other veinlets 2 or 3, ascending. Lamina herbaceous, green when dry, glabrous on both surfaces; rachis green-stramineous, glabrous, deeply grooved adaxially. Sori linear, ascending, slightly curved, up to 7 pairs per pinna, sometimes 1 or 2 pairs in auricle, single (occasionally double), not reaching pinna margin; indusia light brown, linear, membranous, entire, persistent.
