型態特徵
Rhizome dictyostelic, usually stout, erect and covered with persistent stipe bases, rarely horizontal; scales usually thin, ovate-lanceolate and pale brown, rarely narrow and dark brown. Stipe stramineous, tufted, with 2 vascular strands at base uniting into a single U-shaped strand above; lamina usually bipinnatifid to tripinnate, rarely pinnate; texture thin; venation free; rachis and rachillae grooved on dorsal side; often bearing spine - like processes on the upper surface along the costa and or costules. Sori oblong or round, borne along veinlets, usually crossing a veinlet; indusia brown, linear, J- shaped or reniform, margins usually erose. Woodland ferns of temperate regions and on high mountains of the tropics.
About 200 species, 20 in Tawan. This genus needs much more study, differences between some species are small, and variation between fronds of young plants and old ones is often guite large. All Taiwan species grow at altitudes over 1000 m and at higher altitudes they become more abundant.
