Rhizome short-to long-creeping, 0.5–1 mm diam.; scales to 1 mm long, yellowish. Fronds monomorphic. Stipes spaced along rhizome, much shorter than lamina, stramineous, darker at base. Lamina 1-pinnate to incompletely 2-pinnate, linear, 25–30 (–40) cm long, 5–15 mm wide. Pinnae distant, especially towards base; lower and middle pinnae pinnatifid to pinnate; upper pinnae gradually reduced and less divided. Pinnules usually 2–4 per pinna, mostly flabellate, sessile to shortly stalked, 2–5 mm long, 2–6 mm wide; outer margin convex, shallowly crenate to deeply incised; veins free, forked 1–3 times. Sori usually on 2–4 vein endings, separated by incisions; indusium 0.5–0.7 mm wide, whitish, extending to or beyond margin. Spores trilete, medium brown, smooth.
