New plant, what is it?

[walkingtall77]

Hi all, I just bought some new floating plants and have no idea what they are. The people working at the aquarium store didn't know either. Can you guys let me know what they are please. I know the little ones are Amazon frogbit but what are the others

I think it's one of the species of Salvinia, possibly S. cucullata.
