Stems short- to long-creeping, 4–8 mm diam. Leaves monomorphic, evergreen, up to 2(–3) cm apart, (15–)50–160 cm. Petiole straw-colored, (5–)20–80 × (1–)3–6 mm, at base with brown, linear-lanceolate, hairy scales. Blade (9–)30–80 cm, broadest at base, gradually tapered to pinnatifid apex. Pinnae (2–)8–15(–20) × (0.6–)1–2.5 cm, incised 3/5–4/5 of width; segments oblong, rounded to acute at apex; proximal pair of veins from adjacent segments running to sinus, or nearly so.
