型態特徵
Rhizomes creeping or scandent, dorsiventral, rooting only on the ventral surface and two or more rows of fronds on the dorsal surface of rhizomes. Stipes distant or tufted, bearing peltately attached, ovate or lanceolate, brown scales at base, with one or two grooves on upper side and rounded on underside; fronds dimorphic, simple or pinnate; pinnae (when present) entire or deeply lobed, in some cases jointed to the rachises; basiscopic edges of pinnae decurrent on a wing or ridge on either side of the rachises; veins free (simple or once forked) or anastomosing and forming areolae without included veinlets, or with free excurrent veinlets directed away from the costae. Fertile fronds usually with longer stipes and narrower laminae. Sori acrostichoid.

型態特徵
Terrestrial ferns, of moderate size or small; rhizomes creeping, dictyostelic, bearing narrow, dark, entire paleae. Stipes usually approximate, non-articulate, elongate, sparsely paleate, with 2 grooves on upper side, scaley at base; fronds pinnate, rarely simple or bipinnatifid, herbaceous, glabrous; margins crenate to deeply lobed or incised, the sinuses sometimes obstructed by excurrent veins; veins anastomosing, forming areolae with or without excurrent free veinlets. Fertile fronds much contracted, with longer stipes than sterile fronds. Sori acrostichoid, without indusia or paraphyses. Spores globose or nearly so, brownish or hyaline, with thick epispores.
