Emodiopteris Ching & S. K. Wu.
Plants terrestrial. Rhizome creeping, very stout, clothed with multicellular, rather stiff, dark hairs. Fronds homomorphic; stipe grooved above, hairy when young, hairs abscising with age, slightly scabrous; lamina triangular to oblong, many times pinnate, usually densely hairy, especially on rachis, rarely glabrous; pinnules oblique, asymmetrically cuneate at base. Veins free, pinnately branching, veinlet not reaching margin, with hydathode at apex. Sori orbicular, marginal, terminal on each veinlet, separate, usually extrusive from lobes; indusium bowl-shaped, two layers (fused from an internal and external valve), external valve derived from deteriorated lobules or serrations, margin entire, rarely notched, usually ± curved downward like a tobacco pipe, thick; receptacle short, sporangium with slender long stalk, annulus erect, interrupted by sporangiophore at lower part. Spore tetrahedral.
About 70 species: mostly distributed in tropics and subtropics; eight species (two endemic) in China.
