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.

型態特徵
Rhizomes creeping, sparsely paleate when elongate. Fronds usually of indefinite growth, bearing buds in axils of pinnae; stipes approximate or fascicled; laminae pinnate, irregularly proliferous and producing smaller fronds or clusters of fronds in axils of pinnae, firm-herbaceous; forked unicellular hairs present on rachises, costae and veins bearing simple deciduous setulae; veins of adjacent groups joining to form an areole towards the sinus between the lobes (goniopteroid). Sori elongate along the veinlets, exindusiate, mixed with globose-capitate orange paraphyses. Spores bilateral, granular.
