nathantaylor Genus Pectiantia

Combined with Mitella then resurrected under a different taxon ID

This taxon was lumped into Mitella via a taxon swap in 2018 in accordance with Plants of the World Online. The name was later recreated in Oct 2022 under a different taxon ID. Though evidently not accepted in 2018, Pectiantia is currently accepted on Plants of the World Online. This has the potential to cause problems. Is there a way to revert the old taxon swap and then merge the old Pectiantia name with the new one or will this just have to be fixed by manual identification?

I don't think there's a way to "reverse" the swap in the way you're thinking. Swaps forcefully convert IDs, whether or not the original ID is restored is up to the user's settings or discretion post-swap. I chose to create a new Pectiantia to avoid some prior issues I had encountered with the resurrected taxon causing confusion as to the history of changes. Since the first swap was committed prior to taxon history, I wanted to leave a record of changes.

To be clear, swaps can be reversed, but only within a certain time frame following the change. All IDs swapped to Mitella are at Mitella and will stay there unless users change them or a curator were to perform a genus-wide taxon split.

Just cross-referencing the relevant Forum discussion here.

I made an ID link that covers all observations identified as Mitella, excluding observations identified as Bensoniella, Conimitella, Elmera, Heuchera, Lithophragma, Tiarella, Tolmiea, Mitella diphylla, and Mitella nuda, excluding places where the affected taxa are not extant. The resulting link should capture all affected observations with very little unaffected observations slipping through. There are a total of 451 observations.

@ajwright @jasonheadley @citizen1 @stewartwechsler @dougbrown @chrisbrant47 @clabsauce @clairecompton @rick_williams @plachuff @grnleaf you're the top identifiers of these groups. Would you mind taking a look? The URL I posted should get them all, but let me know if I missed anything. iNat cuts long URLs short, so it looks a lot shorter than it actually is.

@ajwright Brewerimitella already exists, I added it back in November: https://www.inaturalist.org/taxa/1424141-Brewerimitella

Oops, comment's gone.

Yeah I realized I hadn't read through the whole shebang...

@ajwright I'm a little too fast for my own good sometimes. I tend to catch people as they add comments, and it's awkward when I reply to something they've edited.

Posted by rynxs over 1 year ago

@rynxs I'm not quite sure what you are asking me to look at.

Posted by stewartwechsler over 1 year ago

The link has observations identified as Mitella, which shouldn't be Mitella following a shift to your western species being distinguished from our eastern Mitella sensu stricto. You may not have noticed the swaps, but your western species under Mitella are not under that genus anymore, so these observations are now technically misidentified and need to be corrected.

The observations that come up for me with that link, are those that are automatically filtered for the greater Puget Trough area (lowlands north and south of Vancouver, BC to Olympia WA), that I mostly do my identifications in, and all are observations that were only identified to genus Mitella, and not species. I didn't find any of them easily identified to species, as I expect I would need to, to get them to their new genera. Removing the Puget Trough filter, I get about 2X as many observations, all identified to genus Mitella, and not to species. A quick look at those, and I wasn't easily able to take them to species. I'm not sure that ajwright didn't beat me to doing something to correct ID'd of some other observations before I found them.

I did find one observation that ajwright identified to species, maybe last night, after your tag, that was initially identified only as "Mitella", with my initial ID species, (Mitella caulescens?), which was switched to the new genus (Mitellastra, if I remember the initial ID correctly), such that the ID of ajwright, together with my initial ID to species, was conflicting with the intitial ID to genus, and our 2 ID's didn't equal a research grade ID (presumably M. caulescens). I posted a comment on that one, indicating it should have been research grade. I tried to find that one again, but didn't succeed.

@rynxs I just found the observation that should have been research grade after the genus was changed, a Mitella changed to Brewermitella, such that the initial ID only to genus Mitella conflicted with the new species Brewermitella ovalis:

@stewartwechsler yes, the intent of the link was to fix the issue of the range of Mitella sensu stricto. The linked observation is at the correct community taxon, as the taxonomic sense of Mitella has been changed from sensu lato to sensu stricto, whereby disagreeing with Brewerimitella. I'm not sure what issue you're having with the link's range, but it works fine for me.
