Ophioglossum vulgatum, commonly known as adder's-tongue,[1] southern adders-tongue or adders-tongue fern, is a species of the plant genus Ophioglossum.[2]

Distribution[edit]

It is native to many regions with a wide scattered distribution: throughout temperate through tropical Africa; and throughout the temperate Northern Hemisphere in Europe, southeastern North America, temperate Asia, and Eurasia.[2][3]

This small, hard-to-spot plant can occur singly in un-improved pastures, rock crevices and grassy path-sides, but also can occur in colonies of hundreds of plants in sand dunes.

Description[edit]

Ophioglossum vulgatum grows from a rhizome base to 10-20 cm tall (rarely to 30 cm). It consists of a two-part frond, separated into a rounded diamond-shaped sheath and narrow spore-bearing spike. The spike has around 10-40 segments on each side.

It reproduces by means of spores.

Uses[edit]

Traditional European folk use of leaves and rhizomes as a poultice for wounds. This remedy was sometimes called the "Green Oil of Charity". A tea made from the leaves was used as a traditional European folk remedy for internal bleeding and vomiting. [4]
