Question
In a seasonal pond in the Blue Hills south of Boston. In spring the plant was under several feet of water. Now the ground is wet but there is no standing water. Also visible in the first two photos is a patch of (probably) Bidens I asked about separately.
Answer
Dear jfc, you have photographed a species of Scirpus (bulrush). The images are too early to tell you which species, but I can state this is part of the Scirpus cyperinus complex (woolsedge group), which is, for common species, comprised of Scirpus atrocinctus (flowers earlier in the summer), Scirpus pedicellatus (flowers between the other two), and Scirpus cyperinus (which flowers later in summer, around now and later). Best wishes.
