Petiole straw-colored, 15–60(–80) cm × 2–7 mm, at base sparsely set with brownish, lanceolate, hairy scales. Blade 20–55(–85) cm, broadest at or near base, gradually to somewhat abruptly tapered to pinnatifid apex. Pinnae 7–20(–26) × 1–2(–3) cm, incised 1/2–4/5 of width, proximal pinnae often narrowed toward base except for slightly enlarged acroscopic basal segment; segments oblique, somewhat curved; proximal 1–3 pairs of veins from adjacent segments connivent at sinus, or meeting margin just above sinus. Indument abaxially of often irregularly crimped hairs ca. 0.2–0.3 mm on costae, veins, and blade tissue, costae also with a few brownish scales less than 0.5 mm; blade tissue abaxially with scattered hairs ca. 0.2 mm. Sori round, medial to supramedial; indusia tan to brownish, usually densely hairy, hairs irregularly crimped, ca. 0.2 mm; sporangia glabrous.
