Plants 80-100 cm tall. Rhizome erect, densely clothed with ovate-lanceolate, brown scales. Fronds caespitose; stipe brown or stramineous at base, 1/4-1/3 as long as lamina, densely clothed with lanceolate, entire, brown scales, these usually appressed; lamina lanceolate, 40-70 × 15-25 cm, once pinnate, base not narrowed, apex acuminate; pinnae 18-30 pairs, remote (lower ones 3-4 cm apart), lanceolate, 10-13 × 1.5-2.5 cm, base truncate, shortly stalked, apex acuminate or caudate-acuminate; segment apices with 1 or 2 beak-shaped teeth. Lamina herbaceous or papery, both surfaces glabrous; rachis and costae clothed with lanceolate or linear, brown scales abaxially, much denser at base of costa; veins pinnate, 3 or 4 pairs per segment, slightly grooved adaxially, distinctly raised abaxially. Sori abaxial on veins and distant from costa; indusia orbicular-reniform, membranous, entire, readily deciduous at maturity.
