, commonly known as moonworts , is a genus of small, fleshy ferns within the Ophioglossaceae family. These unique vascular plants are found worldwide and are often distinguished by their unusual growth form, consisting of a single stalk that splits into two distinct segments: a sterile, leaf-like part called a trophophore and a fertile, spore-bearing part known as a sporophore . Biology and Growth Habits
Moonworts are perennial herbs that typically grow less than 20 cm tall. Unlike most common ferns, they have fleshy, hairless roots and produce a single aboveground leaf each growing season.
