Leaves monomorphic. Petiole blackish to greenish, dull, 1–7(–17) cm, 1/5–1/2 length of blade; glabrous with few scales at base.

Pinnae in (7–)10–15(–20) pairs, oblong, 2-pinnate throughout; medial pinnae (1–)2–3(–6) cm, all ± curved upward; proximal pinnae descending; base cuneate; apex attenuate. Pinnules ± asymmetric, 1–5(–10) × 1–4 mm; margins strongly dentate, cut 1/3–1/2 to axis. Veins free, evident. Sori 1–4(–6) per pinnule, usually on both basiscopic and acroscopic sides.
