Botrypus virginianus, synonym Botrychium virginianum, sometimes called rattlesnake fern is a species of perennial fern in the adders-tongue family.[2] It is monotypic within the genus Botrypus, meaning that it is the only species within the genus. It is called the rattlesnake fern in some parts of North America, due to its habit of growing in places where rattlesnakes are also found.[3][4] Rattlesnake fern prefers to grow in rich, moist woods in dense shade and will not tolerate direct sunlight.
