Agreed. The taller one with the red stem in the picture looks like Ludwigia 'Cuba' to me. It's a bit stunted, but that's what it is.
Really? I ask cause I also got Cuba from the same source, and it looks different (the stem isn't red). I do, however, think that it is maybe some L. inclinata varient that ISN'T cuba, cause I do have cuba and pantanal in this tank now as well.......
So confusing lol
