Thelypteris simulata
Also called Bog fern, Dodge's Shield Fern, Massachusetts Fern
Coryphopteris simulata, synonym Thelypteris simulata, is a species of fern native to the Northeastern United States. It is known by two common names: bog-fern and Massachusetts fern. It is often confused with the silvery spleenwort, New York fern, and the marsh fern due to similarities in shape and size.
Coryphopteris simulata is a terrestrial plant native to Eastern Canada (New Brunswick, Nova Scotia, Ontario and Québec), the North-Central United States (Wisconsin), the Northeastern United States (Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont and West Virginia) and the Southeastern United States (Alabama, Delaware, the District of Columbia, Maryland, North Carolina, Tennessee and Virginia). The isolated patch discovered in southwestern Wisconsin was far outside its expected distribution. Generally speaking, this plant is uncommon.
