Typo in APG IV paper

Just for the record, in the second line of the abstract, there is the incorrect spelling "Metteniusiales" for "Metteniusales". Peter coxhead (talk) 13:17, 13 June 2016 (UTC)

Informal name for members of Pentapetalae

Poster uses Pentapetalae for a "clade". Shouldn't an informal name be used e.g. "malvids"?User-duck (talk) 02:29, 14 July 2017 (UTC)

In my opinion, as long as it doesn't have a ending associated with a rank (e.g. -opsida, -aceae), it's fine for a clade. However, I'm not sure that this article should mention clades that aren't actually mentioned in the APG IV paper. Plantdrew (talk) 16:21, 14 July 2017 (UTC)

Since the poster is the reference for the tree, I was just making sure the article was up to date. I originally noticed the label "core eudicots" was not on the APG IV cladogram.User-duck (talk) 01:54, 15 July 2017 (UTC)

Nitrogen-fixing clade

@Dank:, as far as I can tell, the APGIV paper doesn't mention the nitrogen-fixing clade. I really don't thik this article should not be giving names to clades that were unnamed in the APGIV paper. If these names for unnamed nodes in the APGIV tree are given, it should at least be noted that the names don't come from APGIV. Plantdrew (talk) 02:18, 17 April 2023 (UTC)

Not a problem; I just removed it. Although the APG IV paper itself doesn't name the clade, it does the next best thing ... it names the sister clade, and even casts doubt on its placement. So the paper supports the idea of "Fabids minus the COM clade and Zygophyllales" ... even though it doesn't assign a name to that group. But I don't know what else to call that group; AFAICT, "nitrogen-fixing clade" was the name in circulation during that decade (at, for instance, https://www.mobot.org/MOBOT/research/APweb/orders/zygophyllalesweb.htm#rosids ... the only names I see are "nitrogen-fixing clade" and "n-fixing clade".) Do you prefer a different name for it? (Again, I'm happy to remove the term from this page, but I want to know what to call this group if I have to call it something.) - Dank (push to talk) 02:57, 17 April 2023 (UTC)

I don't think there is any other name for it. Plantdrew (talk) 16:09, 17 April 2023 (UTC)

@Plantdrew, an explanation of how I do and don't use the term is at Talk:List of nitrogen-fixing-clade families#Notes. Your thoughts are welcome (here or there). - Dank (push to talk) 16:40, 17 April 2023 (UTC)
