Plants terrestrial or epipetric. Rhizomes long-creeping, branched, protostelic, with multicellular brown to red-brown, rigid hairs. Fronds erect or pendant, pseudodichotomously branched, branches isotomic, abaxial surface glabrous or pubescent with multicellular white or reddish hairs on the rachis and segments midrib, secondary veins with or without unicellular globose or bacilliform hairs, or with tector hairs, adaxial surface glabrous or with sparse multicellular white or reddish hairs restricted to the rachis, ultimate branches pectinate, segments linear. Buds with pseudostipule entire or trifid, covered by reddish-brown, multicellular, rigid hairs, with or without a pair of accessory branches, entire to pinnatisect. Veins free, 2–3(–4)-forked. Sori round, with 6–15 sporangia per sorus, paraphysiate or not. Spores trilete, whitish, scabrous, rugulose or perforate; x= 39.
