Pteridophytes

The pteridophytes are vascular plants (plants with xylem and phloem) that produce neither flowers nor seeds, and are hence called vascular cryptogams. Instead, they reproduce and disperse only via spores. Pteridophytes include horsetails, ferns, club mosses, and quillworts. They are used for medicinal purposes, as soil -binders, and are frequently planted as ornamentals.
