Rhizome decumbent, sparsely branched, to 370 mm long, to 20 mm in diameter, set with roots and closely to widely spaced persistent stipe bases, the older parts nude, the apical part densely paleated; paleae broadly attached, castaneous to ferrugineous, chartaceous, narrowly lanceolate to narrowly ovate, truncate to cordate, the margins subentire to erose, the apex flagelliform, generally terminating in a small thin-walled cell, to 17 x 3 mm.

Venation adaxially obscure, raised abaxially. Sori circular, c. 1 mm in diameter, terminal or near terminal on abbreviated vein branches, essentially uniseriate, discrete at maturity: sporangium with 10-(12.8)-19 indurated annulus cells; stalk eglandular: indusium peltate, stramineous, castaneous or black, nitid, amorphous to circular, entire to repand, the maximum radius 0.26-(0.5)-0.8 mm in diameter, persistent, brown. Spores pale brown, 64 per sporangium, the perispore folded to form inflated reticulate ridges, the ridges crested, the ridges and areas between sparsely to densely echinulate, variously porate, the exospore 30-(49.31)-62 x 28-(38.08)-56 µm.
Rhizome prostrate, with stipe bases and castaneous to ferruginous, narrowly lanceolate to narrowly ovate scales, subentire to erose. Fronds suberect to arching, up to 1.4 m long. Stipe castaneous, stramineous higher up, with conspicuous larger and smaller scales, larger scales castaneous, narrowly to broadly ovate, minutely erose to shortly fimbriate. Lamina ovate to broadly ovate, 2-pinnate to 3-pinnatifid, with up to 21 pinna pairs. Pinnae ovate-attenuate to narrowly oblong-attenuate, 1-pinnate to 2-pinnatifid. Pinnules firmly herbaceous, proximal acroscopic pinnule largest, inequilaterally ovate, ovate-oblong to ovate-rhomboid or trullate, often somewhat falcate, each subtended by one or more large, often bullate, broadly ovate scales, mostly deeply incised near to costa forming a nearly free auricle acroscopically, serrate to lobate-serrate, aristate, proximal acroscopic pinnule, adaxially sparsely scaled along the costa, abaxially sparsely to moderately scaled.
