| | Re: Please help ID anything aquatic in this pic
Chaotic pics, but here's what I can make out...
photo 1: I see some Hydrocotyle sp., also probably some Alternanthera sp. (not A. reineckii, doubtfully submersible, probably invasive. Maybe A. philoxeroides...).
photo 2: some kind of Sagittaria, may or may not be submersible but definitely a nice pond marginal. Also more Hydrocotyle. Might be a bit of a Ludwigia sp. down at the bottom right corner.
photo 3: Not moneywort - pretty sure it's just a weed of the not aquatic kind
photo 4: the plant with the big, broad leaves is Pontederia cordata, another marginal. The grassy stuff is just grass, and I can't say what the stem plant is without a better photo...
Close-ups of a particular specimen are a lot easier to work with than a big field of weeds - it's hard to see enough of any one plant to ID it properly.
