Description
Ophioglossum vulgatum grows from a rhizome base to 10–20 cm tall (rarely to 30 cm).{{Citation needed|date=April 2024}} It consists of a two-part frond, separated into a 4-12 cm rounded diamond-shaped leaf sheath and narrow branchless spore-bearing spike.{{cite book |last1=Piirainen |first1=Mikko |title=Kotimaan luonnonkasvit |last2=Piirainen |first2=Pirkko |last3=Vainio |first3=Hannele |date=1999 |publisher=WSOY |isbn=951-0-23001-4 |location=Porvoo, Finland |page=26 |language=fi |trans-title=Native wild plants}} The spike has around 10-40 segments on each side.{{Citation needed|date=April 2024}}
Taxonomy
Linnaeus described adder's-tongue with the binomial Ophioglossum vulgatum in his Species Plantarum of 1753.{{cite book |title=Species Plantarum |edition=1st |volume=II |last=Linnaeus |first=C. |authorlink=Carl Linnaeus |year=1753 |publisher=Laurentii Salvii |location=Stockholm |url=https://www.biodiversitylibrary.org/page/359083 |page=1062}}
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.[http://plants.usda.gov/core/profile?symbol=OPVU&mapType=nativity USDA] File:Ophioglossum in sand-dunes.jpg]]
Habitat
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.{{citation needed|date=July 2016}}
In Finland, unlike elsewhere, it grows on seashores, unlike other parts of the world where it tends to be a calciphile. Finland has fitting lime rich soil habitat sparsely, but the plant has found an equivalent living habitat from Finland's seashores affected by a post-glacial rebound: land just risen from the sea is often quite neutral and contains mineral salts in addition to being open and bare enough.
Rarity
This species is rare in most European countries. In Ukraine, there were recorded 280 loci: 152 before 1980, after 1980 – 120, as before and after 1980 – 8 locations.[http://www.myslenedrevo.com.ua/en/Sci/Nature/archive-ophioglossaceae-ukraine/ophioglossum-vulgatum.html: Parnikoza I., Celka Z.

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.{{Cite web |date=2023-02-03 |title=Dr. Duke's Phytochemical and Ethnobotanical Databases at NAL |url=https://phytochem.nal.usda.gov/phytochem/ethnoPlants/show/1556 |access-date=2024-04-17 |archive-url=https://web.archive.org/web/20230203034633/https://phytochem.nal.usda.gov/phytochem/ethnoPlants/show/1556 |archive-date=2023-02-03 }}
