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

One to keep an eye on once it's published.

What about plants that have both red and blue flowers?

Posted by bodofzt about 2 years ago

@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

Posted by graysquirrel about 2 years ago

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.

Posted by carber about 2 years ago

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

Posted by chrise over 1 year ago

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.

Also, L.foemina has long, lanceolate leaves and L.arvensis' are usually shorter and wider

Posted by carber over 1 year ago

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 ?

Posted by botanarchiste 12 months ago

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.

Posted by kevinfaccenda 11 months ago

While we're doing taxon changes on this, we also need to merge all the subspecies on this. None are recognized in POWO. That will have to occur after the split however.

Posted by kevinfaccenda 11 months ago

I added the missing species of the study (Lysimachia talaverae & L. collina). One of them was synonymous with Lysimachia talaverae. It makes one less to worry about.

Posted by nschwab 11 months ago

Please do not merge L. arvensis subsp. platyphylla, this taxon was not studied by JIMENEZ-LOPEZ et al. 2022 !
Probably it would need a full specific rank or a subspecific one under L. loeflingii...

Posted by abounabat 11 months ago

@abounabat Do you have some sort of reference for that? POWO sinks it into L. arvensis.

Posted by kevinfaccenda 11 months ago

I reply you same question : do POWO has any reference for merging ?
I think no and probably the merging is just by "facility" because the last work of Jimenez-Lopez et al. 2022 didn't talk about it...
But I just asked them and will let you know when reply !

Posted by abounabat 11 months ago

Thank you!

Posted by kevinfaccenda 11 months ago

Already replied : it was an old option assumed by Dobignard & Chatelain (2010-2013), thus before my new combination in 2021. Case to be followed...

Posted by abounabat 11 months ago

for reference I'm now cleaning up the Australia observations, also wrote a journal post

Posted by thebeachcomber 11 months ago

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 ?

Posted by t_e_d 2 months ago

should be fine

Posted by thebeachcomber 2 months ago

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 :

Posted by t_e_d 2 months ago

I fixed all Australian observations last year. I'm not really confident IDing outside of Australia given the other blue species that exists

Posted by thebeachcomber 2 months ago

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/1467819-Lysimachia-loeflingii

Posted by abounabat 2 months ago

I revised all observations from Switzerland.

Posted by nschwab 2 months ago
Posted by kevinfaccenda 2 months ago

Not to say "I was right", but there were many cases in the past where people rejected my call to ID blue ones to variety for a future split...

Posted by silversea_starsong 2 months ago

If there are places where all blue lysimachia are L. loeflingii i can help but I am not confident if that isn't the case where there are other blue lysimachia. I don't want to make anything worse.
If you have this case give me a link to a filter or describe filter
cheers

Posted by margl 2 months ago

Yeah there is a real ID issue with loeflingii vs. other "blue" species, although this is only in certain regions.

Posted by silversea_starsong 2 months ago

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

Posted by t_e_d 2 months ago

If the photo is macro enough, you can tell them by the fringe of the petals. But many observations, such as phone photos, cannot tell the distinction.

Posted by silversea_starsong 2 months ago

@abounabat explained something about the shape of the leaves.

Posted by t_e_d 2 months ago

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 ?

Posted by abounabat 2 months ago

Which has the fringed petals

Posted by margl 2 months ago

Got it
