Rhizomes stout, ascending. Fronds caespitose, (45-)100 cm; stipe stramineous, much shorter than lamina, densely clothed with brown, lanceolate scales and multicellular, tortuous, hyaline hairs at base, upward sparsely scaly; lamina pinnate with pinnatipartite pinnae, oblong-lanceolate or oblanceolate, base narrowly cuneate, apex pinnatifid-acuminate; middle pinnae lanceolate, 4-12 cm, base slightly broadened, broadly cuneate or subtruncate, apex acuminate, pinnae alternate, ascending or subspreading, separated; lower pinnae numerous, gradually shortened, 3 or 4 pairs of basal pinnae less than 1 cm, deltoid auriculate; segments (14-)20 pairs, approximate, oblong, adnate to broad wings of costae, subentire or slightly crenate, apex rounded. Veins visible abaxially, pinnate in segments, up to (4-)6 or 7 pairs, simple. Lamina herbaceous when dried, with rather dense tortuous, hyaline multicellular hairs on both surfaces and at segment margins and sinus between segments. Sori shortly linear, approximate; indusia similar to sori, curved, single or double, brownish, long hairy, pilose, or almost glabrate, eroselike or sparsely ciliate at margin. Spores bilateral, perispore surface with rugate, rugate-saccate, or papillate processes.
