Lamina up to 39 × 26 cm, ovate to ovate-oblong in outline, 2-pinnatifid at the apex to 3-pinnatifid at the base, with a pinnatifid to lobed terminal segment and basal pair of pinnae not reduced and basiscopically developed. Ultimate lobes oblong, glabrous on both surfaces, margins crenate to serrate. Rhachis set with a few hairlike scales at the axils of the pinnae. Sori small, round, c. 1 mm in diameter, up to 18 per lobe, exindusiate.
