fern

any pteridophyte plant of the class filicinae, subdivision Pteropsida of the division Tracheophyta, at one time classified in the division Pteridophyta. The ferns constitute the great majority of species in the division and possess large, conspicuous aerial DIPLOID (2) stems. Sporangia are borne on the underside of leaves and the HAPLOID (2) spores usually give rise to homosporous prothalli which carry both ANTHERIDIA and ARCHEGONIA. There is a small group of heterosporous aquatic ferns (see HETEROSPORY).
