Roots proliferous. Stems erect, unbranched; scales brown throughout, linear-deltate, 1.2 × 0.1–0.3 mm, margins entire. Leaves monomorphic. Petiole green throughout, dull, 3–15(–20) cm, 1/3–2/3 length of blade; indument absent. Blade deltate, 1-pinnate, 7–12(–20) × 3–6(–9) cm, thick, papery, glabrous; base not tapered; apex attenuate, not rooting. Rachis green throughout, dull, glabrous. Pinnae in 4–8 pairs, linear-lanceolate; medial pinnae 30–70 × 7–15 mm, slightly curved, strongly excavated in proximal basiscopic 1/3; base with small acroscopic auricle; margins entire to dentate; apex attenuate. Veins free, obscure. Sori 2–9 pairs, medial, commonly 1–2 less on basiscopic side than on acroscopic side. Spores 64 per sporangium. 2n = 72.
