Perennial in soil or rock crevices; rhizome generally short-creeping, ascending, or erect, scales small to large, generally tan to brown, generally uniformly colored.
Leaf: generally tufted or short-spaced, 5–200+ cm, generally ± alike; stipe firm or fleshy (easily crushed), base darker or not, with 2 vascular strands; blade generally 1–3- pinnate, ± glabrous or with hairs, hair-like scales, or gland-tipped hairs on axes, veins generally free (or netted); rachis, costa generally grooved adaxially.
Sporangia: sori round, oblong, J-shaped, or linear along veins; indusia 0 or oblong, J-shaped, reniform, or linear, or of many segmented hair- or scale-like fragments or lobes encircling sorus from below; spores elliptic, winged, ridged, or spiny, scar linear.
± 15 genera, 700 species: worldwide, especially tropics, wooded areas, but some genera (e.g., Cystopteris, Woodsia) generally temperate. See note, reference (Smith et al. 2006 Taxon 55:705–731) under Dryopteridaceae for removal of genera from that family to this. —Scientific Editor: Thomas J. Rosatti.
