The fronds are 25-40 cm tall and 15-25 cm broad, pinnate, with 6-10 pairs of pinnae 4-9 cm long and 2-3 cm broad, deeply lobed, bright green with a dark red-brown stem in the wild plant, with the spore-bearing sori on the underside of the fertile pinnae.
The species name is sometimes cited as "nipponicum".
