Leaves monomorphic, dying in winter, 15–75 × 10–30 cm. Petiole 1/4–1/3 length of leaf, scaly at least at base; scales scattered, tan. Blade light green, ovate-lanceolate, 2–3-pinnate-pinnatifid, herbaceous, not glandular. Pinnae ± in plane of blade, lance-oblong; basal pinnae lanceolate-deltate, slightly reduced, basal pinnules usually longer than adjacent pinnules, basal basiscopic pinnule longer than basal acroscopic pinnule; pinnule margins serrate, teeth spiny. Sori midway between midvein and margin of segments. Indusia lacking glands. 2n = 164.
Habitat: Swampy woods, moist wooded slopes, stream banks, and conifer plantations

Discussion
Dryopteris carthusiana is tetraploid. Dryopteris intermedia is one parent, as indicated by chromosome pairing in their hybrid D. × triploidea Wherry. The other parent is the hypothetical missing ancestral species " D. semicristata " (see discussion for D. cristata). Dryopteris carthusiana hybridizes with five species; hybrids can be separated from D. intermedia by the lack of glandular hairs and by having 2-pinnate leaves.
