I have three plants I could use help identifying. I don't believe any were growing in the water, and I grabbed these a few weeks ago as the wetland was beginning to senesce for winter. Thanks!

First I had to look up the meaning of the word 'senesce'.

Then I asked myself, did you not take photos of the plants in situ? To see the live, green, growing plants would give us a better chance to identify each one.

Other than these specimens, did you take photos? Please say yes.

Also, I see that you are in College Park, MD...but where were the plants growing?

The second one is Winged Monkey Flower (Mimulus alatus).

The third one appears to be a species of Tickseed (Bidens) but I'm not 100% sure of that and, if it is, couldn't make much of a guess at the species.

Sorry! Just that they had begun to die back for winter (the wetlands were in general, I mean), that's what I meant. And unfortunately no, I was in the wetlands, then pressed and dried them for a bit, and now they look the way they do. I can take more pictures of them, however, I just snapped them today. I took these at various wetlands around maryland, as well as Lake Artemesia. If nobody can identify them that's fine as well, I would need to confirm their ID's regardless.
