The quillwort family, also known as the Isoetaceae family, is a group of aquatic or semi-aquatic plants that are primarily found in freshwater habitats. These plants are characterized by their ribbon-like leaves that resemble quills, hence the name 'quillwort'. Other synonyms for the quillwort family include the so-called dragon's-tongue, as well as the 'springworts' as they typically flower during the spring season. The Isoetaceae family includes around 200 species of plants that are known for their incredible adaptability, and their ability to survive in harsh environments such as deserts and salt flats. These incredible plants are an essential part of freshwater habitats, providing food and shelter for many aquatic organisms.
