Hi @jakob, I did not think this warranted a response, but am responding because you also sent me a private message about this again this morning.

This swap seems like a no-brainer and doesn't appear to warrant additional input from other users prior to committing. All the iNat authorities ruling over Trientalis spp. in North America, where all 3 species are found, are calling these Lysimachia and have been treated as such on iNat since Jan 2017. In addition, Plants of the World Online, which iNat is likely to move to once more complete, calls them Lysimachia spp. Looks like Ken-ichi didn't also look at the genus worldwide when he did his swaps, so Trientalis and Trientalis europaea were still active until now. Did you reach out to Euro+Med so that they can update their website? They reference 2011 as the year for their citation. To my understanding it was sunk in 2009. Perhaps it didn't make it in before the last update?

ID 1: Lysimachia
ID 2: Trientalis europaea
Counts as a disagreement at the generic level and at the family level if Lysimachia were categorized within Myrsinaceae on iNat. Seems wrong, no?

Was there something else you wanted me to say or a question you wanted me to answer?

Thanks, I already do that for taxa that are not clear cases, but this is not one of them.
