Please identify (floating plant)

So I bought these on craigs list, the guy said they were 'water lettuce', however, I have doubts, because the biggest ones are old, and look nothing like the water lettuce i've seen.

I was thinking some sort of salvinia, but it has roots... I was thinking salvinia because it has 'hairy' "cat-tongue-esque" leaves.

Please help!

The plant structure appears to me to be the same as water lettuce, Pistia stratiotes. However, your plant is much nicer looking leaves, perhaps a hybrid species? Sorry, I don't know much about this genus and can't offer more although if I have a chance over the next few days I may find something in my references. But for the moment, I do think it is a Pistia species, or if not then something very close. It is not a salvinia in my opinion.

Here's a photo of Pistia stratiotes for reference.

Mine are nowhere near that large.

I've had mine for a month or so, and not only has it completely filled every spot there's not a lilypad or frogbit, it grows to fill the space every time I sell 40 frogbit on ebay, which is weekly.

They are about the size of a dollar coin. You can see the duckweed as a reference in the picture.

The photo was only as a reference to the plant structure, not size. The structure, by which I mean the way the leaves emerge from the crown, the roots, etc., is the same as your plant, but not a salvinia which grows in chains.
