Question
Hello I am in shamokin dam, PA. I live on an old floodplain of the susquehanna river. This plant is along a streambank, and the surrounding area may possibly be a wetland that is not delineated. Historical use may have altered the landscape (drained the wetland) and now it is in a more natural state. There are other OBL species nearby, and I wanted to know if this is a Northeastern Bulrush, or another species of sedge grass. Thanks.
Answer
Dear Penny, good afternoon. These do not appear to be Scirpus ancistrochaetus (northeastern bulrush). That species has characteristic arching branches of the inflorescence (these are quite straight). I do not know who this is from the images supplied, but it may be part of the Scirpus atrovirens complex, which includes S. atrovirens, S. hattorianus, and S. georgianus in the northeast. Best wishes.
