Nuevo estudio filogenético (https://doi.org/10.1101/2021.04.16.440231) del grupo sitúa a L. arvensis como un linaje independiente, ahora llamado L. loeflingii, diferente a L. arvensis, que ahora solo incluye las de flores rojas |

What about plants that have both red and blue flowers?
https://www.inaturalist.org/observations/67597923
@bodofzt That looks like it's probably just both varieties growing together in the same spot, I don't see any sign that they're actually on the same branches
Since A.loeflingii hasn't been already acepted or included in POWO or iNat, both blue and red varieties must be included in L.arvensis yet. Please don't remove the blue flowers' photographs from the L.arvensis page, as it is leading to confusion and many observers are mistakenly identifying them as L.foemina or other.
Are L. foemina and L. arvensis var. caerulea the same thing? They are listed as separate species on POW. See also file:///C:/Users/candj/Downloads/wi.39.39103.pdf
They are separate species, but when L.arvensis has the blue variety photographs removed from its description page, people often mistakenly think that all L.arvensis are red and their observation is a L.foemina, when in fact the blue variety of L.arvensis is usually much more common than this species.
Thanks, I have also worked out some of the differences: "Lysimachia foemina can be distinguished from Lysimachia arvensis on the basis of the hairiness and arrangement of the petals and by the length of the flower stalk. This species has just a few glandular hairs on the margins of the petals, clearly separated from one another (never imbricate). Furthermore the flower stalk is shorter (10 mm (0.39 in)). The colour of the flowers is not a useful diagnostic character.[7]"
I accept that they are separate species and we do not have L. foemina in New Zealand - yet.
But see also https://academic.oup.com/botlinnean/article/199/2/557/6494517 ??
L. loeflingii is now well described as such: https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:3292486-4#synonyms
It's the "blue L. arvensis", not L. foemina.
Coudl you add this new taxon please ?
How many of the blue flowered plants are in iNat only as L. arvensis? Will we have to do a taxon split for all the european observations of L. arvensis and bump them up to the section Anagalis?
It looks like 12k observations. https://www.inaturalist.org/observations?nelat=82.16739068759804&nelng=-168.9729426049619&place_id=any&subview=map&swlat=-11.10829994452789&swlng=-31.46479992805255&taxon_id=791928
This is going to be a rather intensive split since so many observations will need to be reidentified.
@abounabat Do you have some sort of reference for that? POWO sinks it into L. arvensis.
for reference I'm now cleaning up the Australia observations, also wrote a journal post
https://www.inaturalist.org/posts/80958-splitting-of-lysimachia-arvensis-colour-morphs
Update :
Lysimachia loeflingii is now accepted by POWO and has already been added to iNaturalist.
@jimarcor @kitty12 @bodofzt @graysquirrel @carber @chrise @botanarchiste @kevinfaccenda @nschwab @abounabat @thebeachcomber : can this flag be closed ?
I am checking all the observations of Lysimachia arvensis with blue flowers : can someone else check them ? Most of them are still IDed as Lysimachia arvensis :
Link : https://www.inaturalist.org/observations?verifiable=true&ident_taxon_id=1196640&ident_user_id=t_e_dhttps://www.inaturalist.org/observations?verifiable=true&ident_taxon_id=1196640&ident_user_id=t_e_d
I also fixed all non W-Medit ones.
But at least al the L. foemina should be revised, and maybe some L. loeflingii ?
I checked their presented photos at top of screen and they are good :
https://www.inaturalist.org/taxa/792216-Lysimachia-foemina
https://www.inaturalist.org/taxa/1467819-Lysimachia-loeflingii
There are about 1000 obs which need IDs to help push old L. arvensis IDs to maverick:
@galanhsnu @leaf0605 @silversea_starsong @brothernorbert @thebeachcomber @chiuluan @margl @oneanttofew @taiwan_reevesia @chinaberryhuang @jodyhsieh @jeremygilmore
If we all ID a few hundred of these we can help get this taxon cleaned up
I have now checked all observations of « Lysimachia arvensis with blue flowers » in Europe and Africa: can someone else double-check them ?
I may have inadvertantly introduced some confusion between Lysimachia loeflingii and Lysimachia foemina.
And some of them are still IDed as Lysimachia arvensis :
https://www.inaturalist.org/observations?verifiable=true&ident_taxon_id=1196640&ident_user_id=t_e_d
@abounabat explained something about the shape of the leaves.
yes, leaves are another more indication, but not easy to apprehend.
arvensis / loeflingii / talaverae / platyphylla : ovate, obtuse, ligth green
foemina : oblong-lanceolate, subacute, deep green
monelli / collina : lanceolate-linear (and perennial plants !)
@dpavon : am I right ?
See complete key page 572 : https://academic.oup.com/botlinnean/article/199/2/557/6494517
We still have some « Lysimachia arvensis with blue flowers » that are Research Grade here : https://www.inaturalist.org/observations?ident_taxon_id_exclusive=791928,1467819&place_id=any&reviewed=true&subview=table&taxon_id=791928&verifiable=any
One to keep an eye on once it's published.
