Common name


Rhizome long-creeping, slender; rhizome scales ovate in outline, apex tapering to a point, to 3 x 1.7 mm. Fronds monomorphic, spaced, to 80 cm long, herbaceous. Stipe 24–47 cm long, base 5 mm in diameter, decreasing to ± 2 mm below blade, reddish to dark brown, grooved above, near base with narrowly triangular scales to 5 x 1 mm, twisted, otherwise with rather dense hairs to 1 mm long. Lamina 3-pinnate to 4-pinnatifid, deltoid-pentagonal in outline, 30–35 x 25–39 cm, dark green above, mid green below; pinnae 7–10 on each side of the rhachis, near apex gradually grading into decreasing pinnatisect apex; basal pinna pair longest and most divided, each pinna to 24 cm long and curving upward, basal basiscopic pinnule ± 13.5 cm, 2-pinnatifid; second pinna pair with each pinna < 20 cm long, straight, 1-pinnate or with the basal pinnules slightly divided; ultimate segments slightly crenate to almost entire; each segment with a vein with 1–3 lateral veinlets, not reaching margin; rhachis with hairs as on stipe; pinna-costa and costa with dense hairs, glandular, those near branching forks 1.5–2 mm long, smaller on veinlets, insignificant or absent at sinus; upper surface a few large hairs restricted to veins and veinlets. Sori up to 9(–11) per lobe, on veinlets near tip, median, ± 1 mm in diameter; indusium ± 1 mm in diameter, notch to the centre, with ± 8 hairs 0.25–0.45 mm long on margin and ± 8 more such hairs distributed over surface.
