The larger genus, Lemna, I tend to see in very shallow waters, even ephemeral puddles, where there are no larger plants nor fish. Never having seen Wolffia, I can only speculate, but I suspect is is an extreme specialist, surviving in places no competitior can reach. Jason Hernandez Naturalist-at-Large >> Hi Jason, We have quite a few Lemnaceae native here in Michigan. Almost all seem to like quiet back-waters of ponds and lakes where they grow happily entangled among large plants like Nuphar, Nymphaea, Typha, etc. I have seen a Wolffia sp. growing with Spirodela polyrhiza and both Lemna minor and Lemna trisulca - all in the same pond.
