Can anyone help me ID this plant?? Its in the marsh in SWLA. The water is usually about knee high but is almost 2 ft high from all the rain we got from Hurricane Harvey. A few years ago it was full of widgeon grass but dried up during the summer and hasn't had any grass in it until now. Not sure it's widgeon grass b/c of how brown it is...maybe it turned brown from being completely submerged for a few weeks? Thoughts?
