Ophioderma pendulum is sometimes known as the old-world adder's-tongue. In Malaysia, it is known as daun rambu.^[1] It is a fern in the family Ophioglossaceae, and is the type species of the genus Ophioderma. It is most noteworthy for the length of its pendant fronds, up to 14 ft 9 in (4.5 meters) in length and three inches (8 cm) wide produced at intervals along a tree-clinging rhizome.^[2]

Ophioderma pendulum is a common epiphyte in the East Indies.
