Rattlesnake Fern
Botrypus virginianus

About Rattlesnake Fern (Botrypus virginianus) Botrypus virginianus, sometimes called rattlesnake fern, is a low-growing herb in the Ophioglossales, commonly a foot high or smaller. The plant is ternately branched and the leaves feel soft. The stem is bicolor, being pinkish or light tan at the base but greenish nearer the branches or leaves. This is a wide-ranging species. It abounds in many parts of the United States, in the mountains of Mexico, in Australia, in some parts of Asia, as the Himalaya Mountains, and is found also in Norway, in the Karelia region of Finland and Russia, and around Gulf of Bothnia, although in no other part of Europe. It is large and succulent and is boiled and eaten in the Himalayas, etc. It is called Rattlesnake Fern in some parts of North America, from its growing in places where rattlesnakes are also found.
