Common name

Description

Rhizome erect, up to 2 cm in diameter; rhizome scales dark brown with paler margins, lanceolate in outline, entire, tapering to a point, up to 9 mm long. Fronds tufted, arching, thinly herbaceous, up to 1.8 m long, with proliferating buds on rhachis, costae and costules on the upper surface. Stipe 30-75 cm long, straw-coloured to brown, shiny, thinly set with minute white hairs and with scales similar to those on the rhizome at the base. Lamina 30-100 × 23-80 cm, ovate-triangular in outline, 2-pinnatifid to 3-pinnate with long pinnatifid terminal segment, basal pinnae longest and strongly developed basiscopically, sparsely set with minute white hairs on both surfaces, denser on costae and costules and veins below. Ultimate segments oblong-lanceolate, falcate, margins crenate or incised into rounded lobes. Sori up to 2 mm in diameter, round, in regular rows on both sides of the costules; indusia kidney-shaped, c. 1 mm in diameter, brown, membranous.
