adderstongues

Adderstongues, also known as Adder's-tongue or Ophioglossum, are a group of plants belonging to the family Ophioglossaceae. They are characterized by their unique reproductive structures, which consist of a club-shaped sporophyte and a leaf-like gametophyte. The sporophyte produces spores that develop into the gametophyte, which in turn produces gametes for sexual reproduction. Adderstongues are typically found in moist, shady habitats such as forests, woodlands, and along stream banks. They are native to various regions around the world, including North America, Europe, and Asia. The most well-known species is Ophioglossum vulgatum, commonly known as the Adder's-tongue fern. Despite their name, adderstongues are not true ferns but rather a type of fern ally, belonging to the division Psilopsida. They play an important role in their ecosystems by providing habitat and food for various insects and other small animals.
