Plants terrestrial, rarely epipetric; rhizomes short- to long-creeping, erect or decumbent, slender to stout, non-stoloniferous, densely clothed with brownish, lanceolate to linear-lanceolate scales, with entire margins or few teeth; fronds monomorphic; stipes stout, long, dark brown proximally, stramineous distally, scaly at least proximally, then with sparse scales and/or hairs; blades concolorous, lanceolate, oblong-lanceolate, ovate-lanceolate, rarely simple, pinnatifid, pinnate-pinnatifid, or to bipinnatifid, not reduced proximally, apices pinnatifid; rachises scaly to glabrescent; buds present or not; aerophores absent; pinnae not articulate to rachises, oblong-lanceolate, margins entire to spinulose; veins anastomosing and without included free veinlets in both sterile or fertile fronds, forming a regular series of areoles along the costae and costules, ultimate veins free; sori long-linear, sunken, usually confined to costular areoles, arranged on each side of the costae and costules, indusia membranaceus, discrete; x = 31, 34.

Species number, comments, and distribution:— Woodwardia is a north-temperate, amphioceanic genus comprising approximately 13 species. The genus can be distinguished from the other genera in Woodwardioideae by the monomorphic leaves and the usually short-creeping to suberect rhizomes.
