I cant get to my lfs anytime soon, but I have some better pics! And also, the lake marshpennywort, how does it reproduce? And the unidentified plant has roots growing up higher in the stalk, does that help? Oh, and does the LMP like to be partially above water? It looks like its fighting to have its leaves above the water...? Maybe it's looking for CO2 since the only animal is a bladder snail?
