Pteridophyte - Wikipedia
A pteridophyte is a vascular plant (with xylem and phloem) that reproduces by means of spores. Because pteridophytes produce neither flowers nor seeds, they are sometimes referred to as "cryptogams", meaning that their means of reproduction is hidden.

Pteridophytes (Spore Producing Plants: Ferns and More)
Pteridophytes are ancient plants commonly called ferns or fern allies. Pteridophytes are considered a class of plants that fall between bryophytes and seed plants in evolutionary terms. Ferns and their allies are found everywhere, and they are some of the most prevalent plants in certain ecosystems.
Pteridophytes (Spore Producing Plants: Ferns and More)
Pteridophytes are vascular plants that produce spores. These include ferns, horsetails, clubmoss, and spikemoss. Pteridophytes can be distinguished from other spore-producing plants – bryophytes – by their vascular tissue. In addition, they can be distinguished from other vascular plants – gymnosperms and angiosperms – by their lack of seeds.
