Fern Leaves, Ferns and Fern Allies
American Fern Journal, 1910The topic would scarcely seem to be one in need of much discussion, but as morphologists and palaeobotanists have lately added a good deal to our knowledge of the subject, completely changing some of the old conceptions, a brief resume will not be out of place.

A Roadmap for Fern Genome Sequencing
American Fern Journal, 2019. The large genomes of ferns have long deterred genome sequencing efforts. To date, only two heterosporous ferns with remarkably small genomes, Azolla filiculoides and Salvinia cucullata, have been sequenced.

The ferns and fern allies include the ferns, psilopsids, lycopsids, and horsetails (sphenopsids). These are seedless, vascular plants. They have an alternation of generations in which the sporophyte is dominant and has an axis containing xylem and phloem.

Abstract Extant ferns form a monophyletic group of vascular plants (1–8) that number about 10,000 species divided unequally among Ave major lineages—ophioglossoids, whisk ferns, marattioids, horsetails, and leptosporangiates—and recognized in 11 orders and 37 families (9) (Fig. 1). theselineages are all spore-bearing and “seedfree” (10).
