Lygodium microphyllum is commonly known as "small-leaved climbing fern". However, there are several other synonyms used to refer to this plant species. It is also known as Japanese climbing fern, slender-climbing fern, creeping lygodium, and mesh fern. This fern species is native to eastern Asia but has spread to several parts of the world, including North America, Australia, and South America. It is known for its ability to grow vigorously and form dense mats, which can choke other plants and reduce biodiversity in natural ecosystems. Despite its invasive nature, Lygodium microphyllum is also used for medicinal purposes in some cultures.
