[Wikipedia] Native Range, Leaf Identification: Struthiopteris spicant, syn. Blechnum spicant, is a species of fern in the family Blechnaceae, known by the common names hard-fern[3] or deer fern. It is native to Europe, western Asia, northern Africa, and western North America.[1][4] Like some other species in the family Blechnaceae, it has two types of leaves. The sterile leaves have flat, wavy-margined leaflets 5 to 8 millimeters wide, while the fertile leaves have much narrower leaflets, each with two thick rows of sori on the underside.[5] (link added by Mary Ann Machi)
