Ferns are a group of polyphyletic vascular plants that remain at the spore stage and are not considered to be a systematic group. Ferns are generally classified as true ferns, but other ferns include the psilots, lycopods, and horsetails (collectively known as fernallies). *Some of the terminology that mentions "psilotum" is listed below.
