Default Ludwigia Sp. Marilia info needed.

So I received this plant as a freebie in a recent purchase but I can't seem to find any info on it.

The "Marilia" is already kept by some hobbyists in Europe. I've gotten info about that via Facebook, I don't find again the respective postings at the moment, but from my memory:

It is named after the town Marília in Brazil, Sao Paulo state, where it grows abundantly in waters. The owner of a local water plant nursery detected its aquarium suitability and grows it since then.
I've seen photos of the flowering plant, it seems to be something of the Ludwigia peploides or L. grandiflora type: submerged and floating leaves alternate, roundish, narrower emersed leaves, floating stems with sponge-like "pontoon" roots, big yellow flowers (5 petals?).

Addition: I've gotten the info from Fabricio De Oliveira Pereira. The company in Marília is Sunshine Piscicultura.

Looks like L. peploides to me. Interesting that I tried some I collected here and it while it grew submersed, I could not propagate it. If I trimmed a stem, it would not regrow and the replanted top never grew any side shoots. Perhaps it's a better suited local race.

I'm nearly certain now that this is Ludwigia helminthorrhiza. Looked at a bunch of specimens and curiously, many do not show pneumatophores. Vegatatively, it looks totally the same otherwise. I should know for sure this summer when a friend of mine puts some out in his small pond.

Cavan, however what I know as Ludwigia helminthorrhiza from cultivation differs a lot from the "Marilia". I.a. the petals of helminthorrhiza are white with yellow claw, those of "Marilia" (my link further above) entirely yellow, and according to that photo, it seems to develop considerably narrower leaves on emersed shoots than helminthorrhiza.
But with certainty also the "Marilia" belongs to L. sect. Oligospermum ( = sect. Jussiaea). http://botany.si.edu/onagraceae/sect...e=Oligospermum

I'm not convinced it isn't helminthorrhiza, despite some difference in flower color. I'll look into it more when I can, hopefully with a fertile specimen.
