Leaves monomorphic, dying back in winter, 65–120 × 15–30 cm. Petiole 1/3 length of leaf, scaly at least at base; scales scattered, dark brown or tan with dark central stripe. Blade green, ovate-lanceolate, gradually tapering to tip, pinnate-pinnatifid, herbaceous, not glandular. Pinnae ± in plane of blade, lanceolate-ovate; basal pinnae linear-oblong, much reduced, basal pinnules longer than adjacent pinnules, basal basiscopic pinnule and basal acroscopic pinnule equal; pinnule margins crenately toothed. Sori midway between midvein and margin of segments. Indusia lacking glands. 2n = 164.
Habitat: Seepage slopes, hammocks and logs in swamps, mostly on the Piedmont and Coastal Plain
Elevation: 50–800 m

Discussion
Dryopteris celsa is a fertile allotetraploid derived from hybridization between D. goldieana and D. ludoviciana. Dryopteris celsa hybridizes with six species; hybrids can usually be identified by the dark-striped scales.
