Plants evergreen. Rhizome erect, densely covered with lanceolate brown scales. Fronds 10-20 cm; stipe stramineous, 2-6 cm, 1-2 mm in diam. at base, densely covered with scales; scales brown, lanceolate, basal margins with outgrowths; outgrowths hairlike, tortuous and soft; upper margins sparsely fimbriate or subentire. Lamina pinnate, linear-lanceolate or narrowly oblanceolate, 10-20 × 2-4 cm, slightly contracted at base, acuminate; rachis with dense lanceolate scales abaxially, basal margins tortuous ciliate; apex flagelliform, with proliferous bulbil capable of growing into a new plant. Pinnae 14-26 pairs, lower pairs opposite, upper pairs alternate, angled at 90° with rachis or slightly so basiscopically, shortly stalked, oblong or narrowly oblong, middle pinnae 0.8-2 cm × 5-8 mm, bases asymmetrical, apices obtuse or rounded; acroscopic base truncate, distinctly or indistinctly auriculate, basiscopic base cuneate, margins with incurved acute teeth; abaxially scaly; microscales dense or sparse, brown, linear and hairlike, basal margins with outgrowths; outgrowths hairlike, tortuous and soft; frond texture papery; venation pinnate, lateral veins free, indistinct adaxially. Sori often in 1 row close to acroscopic margins, sometimes also on basiscopic side; indusia large, entire.
