Talk:Equisetopsida

Merge
We have articles on taxa, not names. Equisetidae has in the lead "It is equivalent to the class Equisetopsida sensu stricto". The Equisetopsida article makes it clear that it's the same group as Equisetidae, namely one of the groups within "ferns" as broadly defined. The Pteridophyte Phylogeny Group classification has a wide consensus (the paper has a huge list of authors); it uses subclass Equisetidae as the name for horsetails in the broad sense. Raising horsetails to a class or a phylum, as used to be the practice, doesn't fit current molecular phylogenetic approaches, which show that horsetails are well down the hierarchy: Proposal: merge Equisetopsida here, i.e. to Equisetidae.

 * tracheophytes (vascular plants)
 * eutracheophytes
 * euphyllophytes
 * ferns s.l. (class Polypodiopsida)
 * horsetails (subclass Equisetidae)

✅ as there was no dissent, I have made this merger/move. Peter coxhead (talk) 12:44, 28 October 2019 (UTC)
