Stems short-creeping; scales dark reddish brown, concolored, margins entire. Leaves arching to erect, clustered, (15–)35–80 cm. Petiole 1–2 mm diam., minutely rough, abaxially strigose, not glaucous. Blade ovate, pinnate, 1-pinnate distally (small leaves 1-pinnate throughout), (11–)15–35 × (3.5–)8–15 cm, glabrous; proximal pinnae (and sometimes also next 2–3 pairs) 1–2(–3)-pinnate; rachis straight, densely minutely rough. Segment stalks 0.1–0.8 mm, dark color entering into segment base. Ultimate segments oblong, about 2 times as long as broad; basiscopic margin straight or sometimes oblique; acroscopic margin shallowly lobed, lobes separated by narrow incisions; apex obtuse, shallowly lobed. False indusia crescent-shaped, 1–4.5 mm, glabrous. Spores mostly 40–50 µm diam. 2n = 60.
