The treatment here generally follows the Australian National Herbarium but retains the outlying Marattiopsida, Osmundopsida and Gleicheniopsida and classes separtae from the main Pteridopsida.

  • Hey, many of those names are for fern, not pteridophyte. 74.138.55.126 23:04, 28 November 2009 (UTC)
  • This should NOT be Pteridophyta, but Monilophyta, which has been properly named. Jaknouse (talk) 14:30, 7 April 2011 (UTC)
    Based on what? What in the ICBN invalidates the current name (derived from Pteridium) in favor of a name not based on any taxon? --EncycloPetey (talk) 14:39, 7 April 2011 (UTC)
    Pteridophyta is not a valid taxon name, because it is paraphyletic. The preferred terms are Polypodiophyta (Christenhusz & Chase 2014) or Class Polypodiopsida (PPG). --Michael Goodyear (talk) 22:18, 21 November 2019 (UTC)
    Are you claiming that changing the name changes its status as paraphyletic or polyphyletic? Whether a taxon is paraphyletic or polyphyletic is independent of its name. In any case, under the ICN paraphyly is not a reason to reject a name, and Pteridophyta is marked as a legitimate name in the Tropicos database.
    The 2017 ICN 16A.1 recommends: "In choosing among typified names for a taxon above the rank of family, authors should generally follow the principle of priority." The name Pteriodphyta was validly published in 1879 [1], but the name Polypodiophyta was not published until 1966 [2]. Under the ICN recommendation, the earlier name should be preferred. --EncycloPetey (talk) 23:33, 21 November 2019 (UTC)
