Notes on Meaning
While "Pteridophyta" is a well-established term in traditional botany, modern phylogenetic classifications often split this group. The plants are now frequently classified into separate monophyletic lineages (such as Lycopodiophyta and Monilophyta), but the term "Pteridophyta" remains useful as a general, descriptive term for all these seedless vascular plants.
Noun
-
containing all the vascular plants that do not bear seeds: ferns, horsetails, club mosses, and whisk ferns; in some classifications considered a subdivision of Tracheophyta
