Bacopa should have only two leaves per whorl, deeply dissected (therefore looking like many leaves).

Ah, my bad. Yours only looks to have 3-4 "leaf like" projections per node though, while the Bacopa should have at least 10 leaflets sticking out (and all from exactly the same spot, unlike M. pinnatum). Although the pinnatum still has divided leaves in its emersed form, so it might be some other kind of Myriophyllum, unless it looked like this when you got it:

Unfortunately, I have no pics of that supposed Bacopa myriophylloides as it never occurred to me that any questions may arise.
It looked very much like this:
It looked very much like this:
I think I've found it (finally): Myriophyllum simulans. The only one I could find where the emersed leaves where whole and the submersed ones divided. Flowgrow gives a pretty good description:
"The emersed form of Myriophyllum simulans differs clearly from its submersed one: its leaves are not pinnate, have an entire margin and are needle-like to lineal. They grow in whorls on rather thick stems. The submersed form, however, has finely pinnate leaves, much like many other milfoils. They are of a light green colour, the pinna are hair-thin. The stem is also light green and thinner than that of the emersed form, however, in comparison with other milfoils it is still relatively thick."

Lol I said I wasn't 100%.
On picture 2 it looks like the number of leaves per node is random? If that's the case then it should be fairly easy to rule things in or out.
Could well be Ludwigia arcuata.
My guess as well, or some other kind of Ludwigia (like L. brevipes), my plant finding skills usually comes to a stop at genus level 😉 The leaves are too few per whorl for Pogostemon and the pointed leaf ends rule out similar Rotalas at least. If your not in a rush and have some spare space for growing a piece emersed @_Maq_ any flowers should make identification to species way easier.
Ludwigia inclinata var. verticillata "Araguaia"
Ludwigia inclinata var. verticillata "Araguaia" is a local form of the whorly-leaved L. inclinata var. verticillata that reportedly originates from the Rio Araguaia in eastern Brazil. It resembles the more well-known L. inclinata ...

B1, B2: Maybe the pics do not show it clearly enough, so I'll try to stress the very striking feature: From above, the leaves form a perfect CROSS. The leaves are in pairs, and if one pair is in north-south direction, the other is in west-east direction. There surely is a word to name this arrangement (just like there's a word for it in Czech), but I don't know it.
Hi all,
cheers Darrel
There is a botanical term for this leaf arrangement, <"Opposite decussate">.
It is a common leaf arrangement in the Lythraceae, so Alternanthera, Ammannia, Cuphea, Hypericum, Ludwigia, Lythrum etc.
cheers Darrel
Something Ludwigia arcuata have: "spatulate leaves set in pairs and decussate on a fleshy stem with short petioles"
I dont think B1 B2 is in the inclinata var. verticillata group, Maq's plants dont have as many leaves because of the [insert fancy plant word here]
Ludwigia brevipes, Ludwigia arcuata,
Isnt there a few Ludwigia hybrids on the market as well?
"Ludwigia x lacustris" ("natural hybrid of L. brevipes and L. palustris")
"Ludwigia repens × arcuata" ("natural hybrid of Ludwigia repens and L. arcuata) (probably not this one based on leaf shape)
All of these have been stocked by Aquasabi at some point, so they would have been available in Maq's neck of the woods.

A - Definitely a Myriophyllum. Probably Myriophyllum simulans.
B - Not Pogostemon, neither Didiplis. Very likely Ludwigia. Possibly Ludwigia brevipes, rather than Ludwigia arcuata. But I've checked many pics of these and none seems to be exactly like that of mine.
C - Cuphea anagalloidea.
Thank you all very much.
