The ferns (Polypodiopsida or Polypodiophyta) are a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers.
Fern - Simple English Wikipedia, the free encyclopedia
Ferns are a group of about 20,000 species of plants. About 10,000 are living: they are in the division Pteridophyta. [2] Unlike bryophytes, ferns have xylem and phloem, which makes them vascular plants. Unlike seed plants like angiosperms (flowering plants) or gymnosperms, ferns do not have seeds.
