Lamina ovate to somewhat obovate, to 50 cm or more long; pinnae 15–25 pairs, basal 2–4 pairs progressively reduced; basal pinnae c. 4–5 cm long, strongly auriculate on acroscopic base; largest pinnae c. 8–10 cm long, 1.5–1.8 cm wide, lobed half to two-thirds of way to costae; apex acuminate; pinna lobes slightly oblique with rounded tips; veins 8 or 9 pairs; basal veins anastomosing to form an excurrent vein to the short sinus membrane; next acroscopic vein passing to the side of the sinus membrane; lower surface of rachis with 0.2–0.4 mm long hairs; hairs on lower surface of costae and costules mostly to 0.2 mm long; hairs on upper surface of costae 0.5 mm or more long; hairs on upper surface of costules and veins similar, scattered; hairs between veins sparse, very short, both acicular and capitate. Sori medial apart from the lowest ones which sometimes touch those on veins from neighbouring costules; indusium thin, copiously short-hairy.
Widespread across N, NE and SE coast of Australia. Also Palaeotropics and subtropic.
