What are the members of division psilophyta?

Division Psilophyta, commonly known as whisk ferns, includes plants that are primarily represented by the genus Psilotum. These plants are characterized by their simple, leafless stems and dichotomous branching. They lack true roots and leaves, and they reproduce via spores, showcasing a primitive form of vascular plant. Psilophyta is often considered a transitional group between more primitive non-vascular plants and more advanced vascular plants.
