General: Tufted evergreen perennial from a short, thick rhizome.
Leaves: Dimorphic; sterile leaves evergreen, spreading, lanceolate, 10-60 cm long, 2-10 cm wide, pinnately cleft (regularly deeply lobed); fertile leaves erect, narrowly lanceolate, 20-50 cm long, 1-pinnate with linear segments up to 7 cm long, 1-2 mm wide, withering soon after shedding spores.
Notes: Our plants are generally more robust than their European counterpart and are referred by some authors (Love & Love 1966, 1968) to the amphiberingian ssp. nipponicum (Kunze) Love & Love.
