Plants 35-40 cm tall. Rhizomes short and ascending, including stipe bases with dense multicellular acicular hairs and hairy reddish brown lanceolate scales. Fronds clustered; stipes 10-20 cm, grayish brown, with sparse scales and spreading multicellular acicular hairs mixed with unicellular setae on proximal part; laminae lanceolate, 18-27 × 5.2-7 cm, not or slightly narrowed to bases, 1-pinnate, pinnatifid-acuminate at apices; pinnae 8-12 pairs, alternate, obliquely spreading, sessile, proximal 3 or 4 pairs free, distal ones ± adnate to rachises; middle pinnae broadly lanceolate, 4-5 × ca. 1.6 cm, bases broadened, subtruncate, symmetrical, margins crenate or pinnatilobate, apices acute or obtuse. Veins evident, veinlets 3 or 4 pairs, proximal 1.5 pairs joining by their ends, proximal pair arising from far above base of costules. Laminae grayish green or greenish when dry, thinly papery, abaxially with short acicular hairs on intercostal areas, adaxially usually shortly hairy on intercostal areas, with unicellular long setae along both sides of rachises, shortly hairy along costae and veins, with dense appressed setae along adaxial side of costae and sparsely setaceous along veins. Sori linear, attached along veinlets, usually confluent at apices, exindusiate, with remaining glandlike material at attachment of sori; sporangia setaceous near apices.
