Anchistea virginica is a perennial fern of the Blechnaceae family native to North America. 
Anchistea virginica is found along the east coast of the United States, reaching as far west as Texas, as well as eastern Canada. 
A. virginica is commonly found in wetland habitats that include elm and oak populations.  More generally, it can be found in a range of habitats including acidic and organic soils that span from moist to wet in bogs, pocosins, blackwater bottomlands, and occasionally in standing water or periodically flooded depression ponds.
A. virginica has been spotted in post burned areas of Polk County, Florida in association with Cladium jamaicense, and Pontederia cordata car. lanceolata under a stand of Nyssa biflora. In a deep muck seepage swamp in northern Highlands County, Florida, A. virginica has been seen as part of a Sphagnum mat codominated by magnolia virginiana, gordonia lasianthus, and Osmundastrum cinnamomeum as a base landscape for the rare Peltandra sagittifolia. 
As a competitive plant in the canopy of the forest, A. virginica has developed a high density leaf structure to compete for light sources; higher density of leaves results in a larger amount of biomass litter on the forest floor. 
Conservation, cultivation, and restoration
A. virginica is not considered a threatened species; however, it is a rare species in the regions it is present.  It is listed as exploitably vulnerable in the state of New York, a species of special concern in Tennessee, and listed as threatened in Vermont.
