Stems compact, ascending, stout, 5--10 mm diam.; scales uniformly reddish brown, linear-subulate, 0.1--0.3 mm wide, thin, margins sinuous, entire to denticulate. Leaves monomorphic, clustered on stem, 2--40 cm; croziers sparsely villous. Petiole brown, lustrous, rounded adaxially, occasionally with prominent articulation lines near base. Blade linear-oblong to ovate-lanceolate, 1--2-pinnate proximally, 1--8 cm wide; rachis brown throughout, straight, rounded adaxially, nearly glabrous. Pinnae somewhat ascending, decurrent on rachis, usually with 3--7 lobes or ultimate segments; costae when present straight, 1--50 mm, often shorter than ultimate segments. Ultimate segments oblong-lanceolate, 5--20 mm, leathery to herbaceous, glabrous except for occasional hairlike scales abaxially near midrib; margins recurved on fertile segments, covering less than 1/2 abaxial surface, borders whitish, erose-denticulate; apex obtuse. Veins of ultimate segments usually obscure. Sporangia long-stalked, containing 32 or 64 spores, not intermixed with farina-producing glands.
