Rhizome c. 0.5 mm diam., hairy; hairs robust, glossy dark brown, forming tufts at the stipe bases, sometimes extending to the stipe and main rachis. Fronds 4.2–20 cm long. Stipes widely spaced, slender, unwinged or occasionally winged, 0.7–5 cm long. Lamina narrowly to broadly lanceolate, deeply 3-pinnatifid, 2.2–16 cm long, 2–8.5 cm wide, with scattered dark brown medifixed hairs; apex sometimes elongated; lower pinnules often flabellate and ± deeply lobed. Ultimate segments linear, obtuse, 0.7–2 mm wide; margins entire. Sori at the apices of ultimate segments, mostly on acroscopic side of pinnae, ± confined to upper portion of the frond; involucre obovate, bilabiate, divided to the middle, remainder immersed, 2.5–3.2 mm long, 0.7–1.5 mm wide; base cuneate; margins entire; apex obtuse; receptacle long-exserted 0.6–5 mm beyond the valves.
Grows on tree trunks, fallen logs and moist granite rocks along streams in tropical rainforest, microphyll vine/fern forest, notophyll vine forest and stunted montane forest, mostly above 500 m altitude.
