Pointed Broom Sedge (Carex scoparia)
Like other sedges the stems are erect and triangular in cross section. The leaves are slender, light green about 1/8 " inch wide and usually much shorter than the stem. Flowers are straw colored or pale brown and occur on ends of stems and bloom from July to October.
This sedge is found in open swamps, wet meadows and on shorelines throughout much of the United States.
