Here is another Ludwigia species that I am having issues with identifying. Sorry I only have emerged photos of the plant. I will try to take some submerged also.

There are no petals, the leaves are opposite and spade-like. I am thinking Ludwigia palustris.

No, not that. Leaf shape and size, maybe, but not peduncle length, at least not to that degree.
In the article you linked me to in the other thread it states 'In Ludwigia palustris, leaf shape is extremely variable, encompassing much of the total variation among [group Dantia].'

My vote for L. palustris stands.

Update....

Here are some photos of the mystery ludwigia submerged...

From left to right:L.palustris, L.'unknown' (long peduncle), L. lacrustris


Here are 2 other Ludwigia species that are questionable.

From my understanding....plants from left to right: palustris,'long peduncle',lacrustris,arcuata,sp. 'red', 'unknown', 'unknown'


Closer look at the leaves.


L.sp. 'red' in the middle of both 'unknown'


Measurement

That is a gorgeous ludwigia collection you have. I'm jealous lol. I'm guessing hybrid but since I know nothing of nomenclature I will call this Ludwigia lacustris 'inbred'
