Stipe stramineous, densely set at first with small pale hairs c. 0.8 mm. long, becoming glabrous with age. Lamina lanceolate in outline, pinnate in smaller fronds to deeply 2-pinnatifid or rarely 2-pinnate, chartaceous, apex with a prominent deeply crenate cultrate segment grading into petiolulate pinnae; pinnae mostly petiolulate, narrowly triangular often with the lowest segments the largest, acute, sinuate to deeply lobed into sinuate-oblong, obtuse to bluntly acute lobes or rarely cut into subsessile, very narrowly oblong sinuate acute pinnules; ventral surface dark-green almost shining but with curved white hairs set densely along the costa and thinly along the veins; dorsal surface paler dull-green with white hairs up to 2 mm. long on the costa, costules and veins and infrequently in the areoles; rhachis and costa stramineous and pilose with squarrose white scales 2–4 mm. long. Sori up to 2 mm. in diam., mostly semicircular, set in the smaller sinuses but with larger lunulate sori in the larger sinuses; indusia pale, membranous.
