Talk:Gamochaeta coarctata

Requested move 28 December 2023

The following is a closed discussion of a requested move. Please do not modify it. Subsequent comments should be made in a new section on the talk page. Editors desiring to contest the closing decision should consider a move review after discussing it on the closer's talk page. No further edits should be made to this discussion.

The result of the move request was: no consensus. There is no consensus to move the article to Gamochaeta impatiens at this time, as both commenters have raised valid objections based on WP:PRIMARY, WP:CRYSTAL, and WP:RECENTISM. However, there is also no consensus to merge the article with Gamochaeta americana, as this would contradict the current article title and the sources cited by the nominator. Therefore, the best option is to keep the article as it is, but add a note in the lead and possibly create a taxonomy section explaining that Gamochaeta impatiens is a name used by some sources for this species, and also explain further the reasons for the split and the disagreement among the authorities. This would comply with WP:NPOV and WP:V and inform the readers of the current state of the scientific debate. (closed by non-admin page mover) Vanderwaalforces (talk) 17:13, 30 January 2024 (UTC)

Gamochaeta coarctata → Gamochaeta impatiens – This is the new name recognised for this species by Flora of North America (FNA) and the Atlas of Florida Plants (AoFP) based on this paper by Nesom (2022). iNaturalist, while not a taxonomic authority, is also in the process of implementing this split.

Gamochaeta coarctata is still recognised by USDA and WFO Plant List.
PoWo/IPNI, Tropicos, and CoL/GBIF currently treats Gamochaeta coarctata as a junior synonym of Gamochaeta americana.

PoWo will likely recognize this split eventually as well, but I do not see why we could not follow FNA at this point, based on the morphological differences of the south-eastern US adventives.

I disagree with your reasoning because it seems contrary to what an encyclopedia should be. We should not try to anticipate where the scientific consensus will be in two years, later this year, or even next month, but only to follow where it actually is at any given time. Once WFO or POWO changes (even if the other is slow about it) I think that would be the time to for us to move this article. Until then we should definitely say there is a disagreement between botanical sources in the text as to its correct name, and give a strong weight to these very authoritative sources, but wait. I would even call it an uncontroversial technical move once either POWO or WFO changes.

I think it would be entirely fair, even necessary, to have Gamochaeta impatiens listed in the head of the article as a name frequently used by botanists. In addition to being listed down in any Taxonomy section. I suspect people who are not botanical nerds rarely read who named what plant when.

Side note: I went looking to see if there was any other support for the move and it turns out Dr. Michael Hassler's World Plants is another real weirdo in databases this time. Gamochaeta americana (Mill.) Wedd. (1856) is the entry there with Gamochaeta coarctata as a synonym. I've learned to be cautious about citing it. 🌿MtBotany (talk) 03:11, 5 January 2024 (UTC)

• Merge with Gamochaeta americana with Gamochaeta coarctata as a redirect to that. That bit isn't contentious, as that's currently what PoWO says. We shouldn't move (per nom) on the basis of this paper per WP:CRYSTAL. If others start to follow, then that would be the time to reconsider. YorkshireExpat (talk) 20:31, 5 January 2024 (UTC)
