Taxonomic Swap 60575 (Committed on 2019-08-24)

Supporting this change:
1) Most international authorities (including POWO).
The Plant List accepts the name U. vulgaris subsp. macrorhiza based on old data from WCSP. However, WCSP has since been updated and now accepts U. macrorhiza at the species level.

2) All recent scientific literature as far as I can tell.
Utricularia researchers such as Lubomir Adamec, Andreas Fleischmann, Richard Jobson, Bartosz Płachno, Saura Silva, Jan Schlauer, Barry Rice, Donald Schnell, Aaron Ellison, Robert Gibson and of course Peter Taylor all use the name U. macrorhiza in their papers and monographs. The only recent literature I could find using the name U. vulgaris subsp. macrorhiza were regional flora surveys (except for FNA, see below).

3) Many regional authorities and checklists.

Not supporting this change:
1) The Lentibulariaceae treatment in Flora of North America (http://floranorthamerica.org/files/Lentibulariaceae%20provisional.pdf ), as pointed out by @f_rivadavia

2) Some other regional authorities and checklists.

See https://www.inaturalist.org/taxon_changes/5294 for additional discussion regarding this case.

Note that if this taxon swap gets implemented, hundreds of observations will loose their research grade status as they have been identified as U. vulgaris by computer ID.

The only downside I see is the the orphaned records but it probably won't take long before they are are corrected and reach RG, again. Is there no way to convert just the North American records of U. vulgaris to U. macrorhiza?

@rfoster Is there any guideline as to how long taxon change drafts should be left open for comment? This taxon swap is a fairly significant one given that almost 1,000 observations will be affected by it.

Posted by thilokrueger over 4 years ago

I'm not aware of a guideline. You've tagged several people, giving them a chance to comment and nobody has. @bouteloua any thoughts?

Posted by rfoster over 4 years ago

Alright. If nobody adds any comment by then, I will commit the change on Sunday. I am pretty sure the comments will come afterwards ;-)

Posted by thilokrueger over 4 years ago

Yep, go for it! You may get a few squeals of outrage (usually happens with a change like this) but then others like it because they get the chance to go through and correct lots of IDs.

I’m new to how Taxon swaps work and I’m seeing in my feed now an option to update my content. Will this change be automatic or do I need to manually update all my records to U. macrorhiza?

Posted by meganmaye over 4 years ago

@meganmaye It depends on if you have identified your content as U. vulgaris or U. vulgaris subsp. macrorhiza in the past. Unfortunately, only the U. vulgaris subsp. macrorhiza ID's are automatically updated (which has already happened) since U. vulgaris is still very much a valid species and there doesn't seem to be an option to automatically change all U. vulgaris ID's from North America to U. macrorhiza.

Posted by thilokrueger over 4 years ago

@thilokrueger I can now see only one U. vulgaris record for North America and that is an ID by someone who has opted out of community ID. Seems to have gone smoothly.

Posted by rfoster over 4 years ago

Ah, I see that there are lots that are now in limbo because you and Fernado have been very busy identifying to subspecies prior to the swap. I have little doubt they'll be fixed soon as it's often only the observers original ID that is preventing RG as U. macrorhiza.

Posted by rfoster over 4 years ago

@rfoster Yes, that certainly went much more smoothly than I expected! Of course, there are now a few hundred observations which have reverted to genus ID mostly due to the observer selecting U. vulgaris in the computer ID options. Hopefully many of them will be fixed soon. I have also added atlases for both taxa which should help clarifying the disjunct geographic distribution of the two.

Posted by thilokrueger over 4 years ago

@thilokrueger thanks! I’ll check back on my previous observations and see if any need updating.
