Plants medium-sized, on soil. Rhizomes short, erect or ascending, with dense unicellular or multicellular long hairs and sparse brown setaceous lanceolate scales. Fronds clustered; stipes dark brown, bases scaly and with grayish white unicellular or multi-separated acicular long hairs; laminae oblong-lanceolate or broadly lanceolate, not narrowed to bases or slightly so, 1-pinnate, pinnatifid-acuminate at apices; pinnae ca. 10 pairs, spreading, sessile or very shortly stalked on proximal several pairs, distal ones ± adnate to rachises, lanceolate or ovate-lanceolate, rounded-cuneate or truncate at bases, subopposite, undulate or crenate along margins, or lobed to 1/3 of distance to costule, shortly acute or rounded-obtuse at apices, sometimes acuminate, both surfaces ± with hairs, costae obviously raised abaxially, grooved adaxially, with dense acicular hairs. Veins goniopteroid, 3-5 pairs of veinlets per segment, proximal 1-3(-5) pairs joining to form triangular areoles, proximal pair arising above bases of costules, distally veins all reaching margin above sinuses. Laminae herbaceous, dark brown-green when dry, abaxially with grayish white acicular hairs, adaxially sparsely setaceous; usually with multicellular long hairs and short hairs along rachises. Sori linear, attached along veins, exindusiate or sometimes indusiate; sporangia bearing erect short hairs, sometimes glabrous; spores bilateral, elliptic, sharply echinate.

More than ten species: SW China, India, Malesia, Myanmar, Vietnam; six species (five endemic) in China.
