型態特徵

Terrestrial ferns; rhizomes usually creeping but not dorsiventral in structure, dictyostelic; rhizome-scales usually rigid, not peltate at the base, bearing unicellular needle-like hairs on margins and often on surfaces. Stipes containing 2 vascular bundles at the base and uniting to form a single strand U-shaped in section; laminae usually oblong or narrowly elliptic in outline, bipinnatifid, rarely bipinnate; surfaces bearing slender unicellular or rarely 2-celled hairs, sometimes also short glandular hairs; costae raised on upper surface at base, grooved or not, if grooved, not open to the groove of rachis; veins all free, pinnately arranged in each lobe of pinnae, or with veins of adjacent groups joining to form an areele towards the sinus between the lobes; sinuses closed at the base by a translucent membrane. Sori usually subapical on the veins, round or somewhat elongate; indusia renifonm, rarely naked. Spores always bilateral with perispore.
