Contents
Distribution
It is native to many regions with a wide scattered distribution: throughout temperate through tropical Africa; and throughout the temperate Northern Hemisphere in Europe, northeastern North America, temperate Asia, and Eurasia.
This small, hard-to-spot plant can occur singly in unimproved pastures, rock crevices and grassy path-sides, but also can occur in colonies of hundreds of plants in sand dunes.
Description
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
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.
