Stems erect, 4–12 mm diam. Leaves monomorphic, evergreen, clustered, (15–)75–125(–200) cm. Petiole (5–)15–50(–100) cm × (1–)2–9(–12) mm, at base with tan (whitish when young), ovate, glabrous scales. Blade (8–)25–75(–100) cm, broadest at or near base, tapering gradually to pinnatifid apex. Pinnae (3–)10–32 × (0.5–)1–3(–4) cm, incised 3/4 or more of width; segments oblique, somewhat curved, basal segments elongate parallel to rachises or acroscopic segment of a pinna enlarged and dentate; proximal pair of veins from adjacent segments running to sinus or meeting margin just above sinus.
