About Coastal Wood Fern (Dryopteris arguta) Dryopteris arguta is a species of wood fern known by the common name Coastal woodfern. It is native to the west coast of North America, where it grows in oak woodlands and shady low elevation slopes. The species is somewhat variable in appearance. Leaflets sometimes turn at an angle from the leaf, giving it a ruffled or lacy look, and the toothed leaflets may have bristles at their tips. According to C. Michael Hogan, The thin concave indusia are quite closely spaced and almost entirely cover the sporangia.
