Talk:Equisetum
From Wikipedia, the free encyclopedia
..."the only genus in the family Equisetaceae, in the order Equisetales, in the class Equisetopsida, sometimes placed in its own division, Equisetophyta, or in the division Tracheophyta or Archeophyta."
Have I understood this right? Is this the only genus in the order, class and (possibly) division? If so, all 3 of those levels should be bolded in the taxobox and the opening para, and we should have redirects from all 3 of them, because this is the defining page for them all. But although I have contributed to this page, I don't know enough about this plant to risk doing that - I only got involved with the page because I was doing one about Hippuris and ran into the ambiguity. Could someone who knows more about it make these changes if appropriate? thanks.

No, you're absolutely correct in terms of living plants. There are other classes and orders, but they're only fossils. jaknouse 16:05, 4 Mar 2004 (UTC)
- Thanks. I've now adjusted to treat this page as defining for the family and order, but left open the class and division, since we might some time acquire pages on fossil members. seglea 16:59, 4 Mar 2004 (UTC)
Regarding Tracheophyta--this is a group that's a bit ambiguous with regards to whether you want to call it a division or whatnot. Basically, it's somewhere between division and kingdom and includes all vascular plants. Equisetopsida has always been a tracheophyte, but different people vary in whether they give Equisetopsida its own division, lump it into Pteridophyta, etc., and in what hierarchical level they want to call the tracheophytes. I've changed things slightly to reflect this. Paalexan 22:44, 16 November 2005 (UTC)
[edit] Equisetum japonicum
I'v got Equisetum japonicum in my pond, but it isn't mentioned here as a species. Is this really an existing species or not? Tbc2 19:54, 23 October 2005 (UTC)
- Checked up - it is usually treated as a synonym of Equisetum hyemale - MPF 10:50, 17 November 2005 (UTC)
[edit] Equiseta
Flora de Chile considers E.giganteum and E xylochateum the same taxon. --Penarc 18:16, 13 April 2007 (UTC)--Penarc 01:52, 21 April 2007 (UTC)
[edit] Discrepancies
Between the Equisetum page and the Vascular Plant page ( http://en.wikipedia.org/wiki/Vascular_plant ), Equisetum is listed under Pteridophyta and Equisetophyta respectively. As I am a new member (for I only registered to query this) I am unsure how to change this. If anyone has the research to back up one or the other division, could he or she edit the discrepancy? Thanks.

- There is recent speculation that Equisetum actually belongs in the Pteridophyta division. I am unsure how do deal with this situation as well. Snafflekid 20:32, 3 August 2007 (UTC)
- Digging around, as of 2006 there is a proposal for new classification of ferns [1], which is keeping the placement in flux. Snafflekid 21:12, 3 August 2007 (UTC)
