Description from Flora of China

Plants terrestrial, sometimes climbing. Rhizome usually long creeping, solenostelic, siphonostelic, or polystelic, usually covered with multicellular hairs, less often with few-celled, cylindrical, glandular hairs or multicellular bristles, scales absent. Fronds medium-sized to large, sometimes indeterminate, monomorphic; stipes not articulate to rhizome, usually hairy, rarely glabrous; lamina 1-4-pinnately compound, thinly herbaceous to leathery, hairy or glabrous, without scales; rachis grooved adaxially, sometimes with buds (Monachosorum); pinnae opposite or alternate; veins usually free, pinnate or forked, not reaching margin, reticulate without included veinlets in Histiopteris. Sori marginal or intramarginal, linear or orbicular, terminal on a veinlet or on a vascular commissure joining apices of veins; indusia linear or bowl-shaped, sometimes double with outer false indusium formed from thin reflexed lamina margin and inconspicuous inner true indusium; paraphyses present or not. Spores tetrahedral and trilete, or reniform and monolete, spinulose, tuberculate, or smooth. Gametophytes green, cordate. x = 26, 29, 30, 31, 33, 34, 38, 46, 47, 48, and probably others.
