Rhizome short- to long-creeping, 1–2.5 mm diam.; scales narrowly triangular, to 2 mm long, pale reddish brown. Fronds monomorphic. Stipes distant, 10–35 cm long, usually shorter than lamina, stramineous to reddish brown. Lamina often 1-pinnate-pinnatifid or 2-pinnate, 15–45 (–50) cm long; basal pinnae 3–10 times longer than wide. Lateral pinnae spreading, scarcely ascending, gradually and strongly reduced towards apex. Terminal pinna lobed or pinnatifid, much smaller than laterals. Pinnules ±diamond-shaped or obovate; apical segment usually elongate and ±undivided; midrib not distinct. Sori continuous except where broken at marginal incisions; occurring only on the outer margin of small pinnules of 2-pinnate laminae. Indusium 0.3–0.5 mm wide, often with an uneven margin. Spores trilete, pale brown.

Widespread in tropical and subtropical Australia. Also widespread in the Palaeotropics.

Terrestrial in a wide variety of forested and open woodland habitats, often near creeks or soaks.
