Editing Ophioglossum (section)

==Description==
Adders-tongues are so-called because the [[spore]]-bearing stalk is thought to resemble a [[snake|snake's]] tongue. Each plant typically sends up a small, undivided leaf blade with netted venation, and the spore stalk forks from the leaf stalk, terminating in sporangia which are partially concealed within a structure with slit sides.<ref name="efloras"/>

When the leaf blade is present, there is not always a spore stalk present, and the plants do not always send up a leaf, sometimes going for a year to a period of years living only under the soil, nourished by association with soil [[fungus|fungi]].

The plant grows from a central, budding, fleshy structure with fleshy, radiating roots.

''[[Ophioglossum malviae]]'' is known as the world's smallest terrestrial fern.<ref>{{cite journal | doi=10.1038/s41598-018-24135-2 | title=Discovery of the World's Smallest Terrestrial Pteridophyte | date=2018 | last1=Patel | first1=Mitesh | last2=Reddy | first2=Mandadi Narsimha | journal=Scientific Reports | volume=8 | issue=1 | page=5911 | pmid=29651115 | pmc=5897345 | bibcode=2018NatSR...8.5911P }}</ref>
