Question
Aquatic plants forming a mass of green and brown at the edge of a pond in Lincoln, Massachusetts. My ID is Scirpus cyperinus.
Answer
jfc, this does look like Scirpus cyperinus, which is the later flowering of the species in the complex. It is both morphology and phenology that help identify this species. Best wishes.
