Leaves monomorphic, green through winter, 6–40 × 1–6 cm, old leaves persistent as gray or brown conspicuous clump at plant base (only in this species). Petiole 1/3 length of leaf, scaly throughout; scales dense, brown to red-brown. Blades green, linear-lanceolate, pinnate-pinnatifid to 2-pinnate, papery, densely scaly (only in this species) abaxially, glandular, aromatic when handled (only in this species). Pinnae ± in plane of blade, linear-oblong; 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 glandular. 2n = 82.
