Stems short-creeping to nearly erect; scales dark reddish brown, concolored, margins entire or minutely denticulate. Leaves arching or pendent, densely clustered, 20–62 cm. Petiole 0.8–1 mm diam., glabrous, occasionally glaucous. Blade ovate, pinnate, 15–38 × 8–26 cm, gradually reduced distally, hirsute; proximal pinnae 3–4-pinnate; rachis straight or becoming flexuous, glabrous, not glaucous. Segment stalks 1–4 mm, dark color ending ± abruptly at segment base. Ultimate segments transversely oblong, nearly round, or fan-shaped, about as long as broad; base truncate or cuneate; margins of fertile segments crenulate or entire, sterile segments with margins serrulate; apex rounded. Indusia transversely oblong or crescent-shaped, 0.5–4 mm, covered with whitish needlelike trichomes. Spores mostly 35–53 µm diam.
Phenology: Sporulating late winter–early spring.
Habitat: Moist, shaded, limestone cliffs along streams and rivers, on boulders in creeks, and among rocks on steep slopes
Elevation: 200–500 m
Distribution
