A terrestrial fern growing in colonies in mountain wetlands and similar places.
It has a short creeping rhizome.
The leaves are of two kinds, sterile and spore-bearing; the sterile leaves are ovate-lanceolate, 30–80 cm long and 15–25 cm wide, and bipinnately deeply lobed.
The pinnae are 5–20 cm long and 1.5–3 cm wide, pinnately cut, with hairs on the margins of the lobes, mixed with black hairs.
The pinnae have no stalks.
The spore-bearing leaves are shorter than the sterile leaves and bipinnately deeply lobed.
The pinnae are 2–4 cm long and 1.5 cm wide, deeply pinnately cut, and the lobes are 0.2–0.4 cm wide.
The sporangia cover the entire surface.
The spore-bearing leaves wither before summer.
The young shoots are covered with reddish brown soft hairs.
