Trophophore stalk 4–20 cm, 2–2.5 times length of trophophore rachis; blade green to dark green, plane, 2–3-pinnate, to 18 × 28 cm, herbaceous. Pinnae to 7 pairs, usually remote, horizontal, distance between 1st and 2d pinnae not or slightly more than between 2d and 3d pairs, undivided except in proximal 2/3–1/2. Pinnules elongate, obliquely lanceolate to narrowly lanceolate, margins nearly parallel and finely denticulate, apex short-acuminate, venation pinnate. Sporophores 1–2-pinnate, 2–3 times length of trophophore. 2n =90.
Phenology: Leaves green over winter, sporophores seasonal, new leaves appearing in late spring–early summer.
Habitat: Frequent in low woods and brushy fields
Elevation: 0–600 m
