Information Rhizome short, creeping, with tufted fronds and with shining ferrugineous minutely serrate very narrowly linear attenuate rhizome scales up to 1 cm. long with paler margins. Stipe atrocastaneous, terete, glabrous dorsally at maturity, pubescent ventrally in upper parts and with some pale-brown scales similar to those on the rhizome about the base. Frond erect, coriaceous. Lamina up to 18 x 14 cm., triangular in outline, 3-pinnate with the basal pinnae 2-pinnate, somewhat developed basiscopically; pinnules of central pinnae, c. 1 x 0.3 cm., very narrowly oblong, entire, obtuse, with a cordate base, glabrous on both surfaces, articulated to the apices of the petiolules; veins free, obscure; rhachis and secondary rhachises atrocastaneous, terete, shortly pubescent ventrally, glabrous dorsally. Sori forming a marginal line; indusium continuous, erose, membranous.

Information Rhizome shortly creeping with dense chestnut linear-lanceolate scales up to 8 mm long, 0.5 mm wide, slightly ciliate. Fronds 10–15, tufted, 40–75 cm tall; stipe chestnut to black-purple, 19–30 cm long, densely ± reflexed-scaly below, and together with rhachis densely covered with multicellular hairs which are brown at the joints and shortly pubescent, but ± glabrous on lower surface; lamina triangular in outline, up to 19 cm long, 16 cm wide, very distinctly bipinnate with basal pinnae up to half the length of the lamina; lowest pinnules of basal pinnae sometimes with 2–3 ultimate segments and thus the lamina very slightly 3-pinnate; pinnae in 12–14 pairs, the upper 10 or fewer pairs not divided, the lower 2–4 pairs 9.5–19 cm long, 5–6 cm wide, again pinnate; pinnules in 2–11 pairs, oblong, oblong-elliptic or triangular-lanceolate, 1.4–7.5 cm long, 0.3–2 cm wide, rounded to subcordate at the base; stalklets with similar hairs to rhachis; young pinnules and sterile apices of mature pinnules strongly crenulate; venation visible by clearing or transmitted light, entirely free or with 1–2 anastomoses near base of pinnules on each side. Sori and indusium continuous.
