Rhizome wiry, brown to black and shiny, naked, 2 mm in diameter. Fronds erect, oblong in outline, 0.3–1.4 m tall, coriaceous. Stipe matt, brownish straw-coloured, 13–18 cm long, glabrous. Rhachis continuing growth through up to 2 false dichotomies. Pinnae suberect, broadly lanceolate in outline, up to 14 × 5 cm; tufts of brown hair-scales 1.5(–4) mm long in the axils of the false dichotomies and sparsely on the pinnae costae. Pinnules up to 38 pairs per pinna, linear-attenuate in outline, to 3 × 2.5 cm, hairless, divided to the midrib into up to 25 pairs of rounded triangular lobes up to 1.5 × 1.5 mm. Sori solitary, not sunken, at the end of simple veins, consisting of 6–14 sporangia.
