Rhizome long creeping, 3–5 mm diam., very densely scaly throughout; scales stiff, subdeltoid with round base, or narrower, 4–7 by about 2 mm, nearly black on central portion of abaxial surface, deep brown in other parts, shining, with irregularly toothed thinner margin. Stipes jointed to rachis on distinct scaly phyllopodia, stramineous or brown, 7–14 cm long, sparsely scaly with scales similar to those on rhizome but smaller and more or less thinner. Laminae deeply pinnatifid, oblong, ovate, up to 17 cm both in length and breadth; rachis and costae distinctly raised on both surfaces, rarely scaly; lateral lobes 4–7 pairs, deeply lobed with wings of rachis 2–6 mm in breadth, basal 1–2 pairs deflexed, the others ascending, up to 9 by 1.5 cm, the margins parallel and gradually narrowing near the apex towards acuminate apex, shallowly serrate at margin, main veins distinct, 3–4 mm from each other, the other veins hardly visible, reticulate forming irregular anastomosis with included free veinlets, papyraceous. Sori one between adjacent main veins, in a single row at each side of costa, close to costae, round , up to 3 mm diam., hardly raised on upper surface.
