Lygodium (climbing fern) is a genus of about 40 species of ferns, native to tropical regions across the world, with a few temperate species in eastern Asia and eastern North America. They are unusual in that the midrib of the frond is thin, flexible, and long, the frond unrolling with indeterminate growth and the rachis twining around supports so that each frond forms a distinct vine. The fronds may be from 3–13 metres long, depending on the species. It is considered an invasive weed in many places because of its fast growth rate. In the Philippines, it is called “Nito” and widely harvested for crafts. The shade difference between the outer bark and inner bark are often made use of as a decorative effect.
