Note that your specimen examples have no rhizomes to speak of, much less long thick horizontal ones. N. peltata does not even have rhizomes.
I found this "Nymphaea-like" Villarsia. This might do the trick although i would still like to see a good photo of a rhizome of this species as it does not match as well from the drawing.
