R. rotundifolia grows in several different colors and forms, and can
change forms on a single stem.  According to Rataj and Horeman Rotala
indica and Rotala rotundifolia are synonyms for the same plant.
"rotundifolia" (the name refers to the form of the emersed leaves) is the
senior synonym.

The "narrow leaf macrandra" sounds like what I've seen sold as rotala
