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.
Genera In Family: +- 15 genera, 700 species: worldwide, especially tropics, wooded areas, but some genera (e.g., Cystopteris, Woodsia) generally temperate. Note: See note, reference (Smith et al. 2006 Taxon 55:705--731) under Dryopteridaceae for removal of genera from that family to this.

Athyrium filix-femina (L.) Roth var. cyclosorum Rupr.
NATIVE
Leaf: blade elliptic to lanceolate, 1--2-pinnate-pinnatifid, lower 2--4 pinna pairs generally << those above, ultimate segments pinnately lobed to +- toothed, midribs below near base often with minute, branched hairs 0.1--0.2 mm. Chromosomes: 2n=80.
