Description:
Rhizome erect to suberect, up to 7 mm in diameter; rhizome scales brown, up to 9 mm long, lanceolate in outline, margin entire, tapering to a drawn-out point. Fronds tufted, arching, herbaceous. Stipe up to 53 cm long, straw-coloured, reddish-brown near the base, densely set with stiff dark brown scales standing out at right angles to the stipe. Lamina up to 50 × 40 cm, 3-pinnate to 4-pinnatifid on the basiscopically developed basal pinnae, deltate to roughly ovate in outline. Pinnae narrowly oblong-attenuate, spaced apart, almost equally sided. Ultimate lobes oblong, margins weakly lobed or entire, apex lobed or entire, rounded, subglabrous with few brown, upright scales above and below. Rhachis straw-coloured, set with scales similar to rhizome. Sori round, up to 1.2 mm, 12-20 per lobe set in the upper half of the pinnules; indusium kidney-shaped to subcircular, c. 1mm in diameter, membraneous, entire.
Notes: Can be distinguished from other Dryopteris-species by having a combination of stiff scales that stand out at right angles on the stipe, entire rounded pinnule lobes and sori that are grouped towards the end of the pinnules.
Derivation of specific name: squama: scale, seta: bristle; refers to the stiff scales on the stipe.
