While Pteridphyta is a deprecated term due to being paraphyletic, a large number of pages have navboxes which point to this page. Therefore it is worth spelling out the history and current treatment of this group here. --Michael Goodyear (talk) 15:16, 20 April 2017 (UTC)[reply]

The page doesn't have to cover the taxon "Pteridophyta", just the English term "pteridophyte", with additional explanation. The word still show up in nunerous articles and textbooks, even though it is not longer recognized as a taxon. It's just going to be a long slow road to figure out what the article should cover. Thanks for stepping in and getting the changeover started! --EncycloPetey (talk) 17:08, 20 April 2017 (UTC)[reply]

There was a recent discussion about shifting ferns over to using automatic taxoboxes. There's been little progress so far, but it's something I aim to work on in the next few weeks. Currently, ferns using automatic taxoboxes have a piped link that display Pteridophyta, but pipes to Fern. I'm not entirely sure that is the best way to do things, but the advantage of using automatic taxoboxes is that it is very easy to change the taxonomic hierarchy in a large number of articles with a small number of edits. Shifting to automatic taxoboxes will reduce the number of links to this page. Plantdrew (talk) 20:16, 27 April 2017 (UTC)[reply]

science

A pteridophyte is a vascular plant (with xylem and phloem) that disperses spores. Because pteridophytes produce neither flowers nor seeds, they are sometimes referred to as "cryptogams", meaning that their means of reproduction is hidden. Ferns, horsetails (often treated as ferns), and lycophytes (clubmosses, spikemosses, and quillworts) are all pteridophytes. However, they do not form a monophyletic group because ferns (and horsetails) are more closely related to seed plants than to lycophytes. "Pteridophyta" is thus no longer a widely accepted taxon, but the term pteridophyte remains in common parlance, as do pteridology and pteridologist as a science and its practitioner, respectively. Ferns and lycophytes share a life cycle and are often collectively treated or studied, for example by the International Association of Pteridologists and the Pteridophyte Phylogeny Group. 139.5.27.169 (talk) 17:31, 11 February 2022 (UTC)[reply]

I assume "pteridophytes" is meant. A sorus, defined as a cluster of sporangia with or without an overall covering (indusium), is a characteristic of ferns, rather than all all "pteridophytes". Peter coxhead (talk) 17:26, 15 February 2022 (UTC)[reply]
