The Family Psilotaceae is a group of ferns commonly known as whisk ferns. There are not many synonyms for this family, as it is a distinct and recognizable group. Other than Psilotaceae, the family is also sometimes referred to as the Psilophyta, which is derived from the genus Psilotum. The plants in this family are unique in their lack of leaves and roots, and their unusual branching. Some species, like Psilotum nudum, are used in traditional medicine and have been studied for their potential therapeutic properties. Despite their odd appearance, whisk ferns are an important part of the plant kingdom and offer insights into the diversity of life on earth.
