Stems usually long-creeping, 1.5–2.5 mm diam. Leaves monomorphic, dying back in winter, mostly evenly spaced 1 cm or more (sun-gathering leaves in loose cluster), (25–)40–85 cm. Petiole straw-colored, 4–25 cm × 1–3 mm, at base with scales tan to reddish brown, ovate, glabrous. Blade elliptic, 15–60 cm, proximal 4–10 pinna pairs gradually smaller toward base (smallest often less than 5 mm), blade tapering gradually to pinnatifid apex. Pinnae deeply pinnatifid to within 1 mm of costa, 3–9(–13) × 1–2(–2.5) cm; segments oblong to linear, somewhat oblique, entire to crenulate; proximal pair of veins from adjacent segments meeting margin above sinus. Indument abaxially of moderately to densely set hairs to 1 mm on rachises, costae, and veins, glands lacking or yellowish to light orangish, mostly sessile on blade tissue; blades adaxially often with hairs on veins. Sori round, supramedial; indusia tan, often ciliate; sporangia glabrous. 2n = 54.
Habitat: Terrestrial in moist woods, especially near swamps, streams, and in vernal seeps of ravines, often in slightly disturbed secondary forests, frequently forming large colonies
