Marsilea, Ferns, and Horse-tails are examples of plants belonging to the group Pteridophyta. This group includes ferns and their close relatives (fern allies).
Pteridophytes are vascular plants (having xylem and phloem for transport) that reproduce via spores, not seeds. They show alternation of generations, with the sporophyte being the dominant, conspicuous plant. Bryophytes (mosses, liverworts) are non-vascular spore-producing plants. Gymnosperms and Angiosperms are seed-bearing plants, with Angiosperms also producing flowers and fruits.
Marsilea is a type of aquatic fern. Ferns are the most diverse group of pteridophytes. Horse-tails (Equisetum) are also spore-bearing vascular plants and are considered fern allies within the Pteridophyta.
