Pteridophytes: The Ferns, Club Mosses, and Horsetails

In Bryophytes, the conspicuous generation is the gametophyte. In Pteridophytes, we find a reversal of roles. The conspicuous generation is the sporophyte, and the gametophyte is small and often unseen. This is true of all higher plants. The members of Pteridophytes have vascular tissue, but they do not form seeds.
