Bristleleaf sedge (Carex ebenea) belongs to the Cyperaceae (the Sedge family). It is a perennial herb that is native to the eastern and central United States. This grass grows in cliffs, balds, or ledges, woodlands, and up to a height of 15-30 cm. The leaves are linear, alternate, and mostly near the base. They are hairless and typically roll up along the edge. The whitish-green flowers bloom on spikes in spring. Fruit develops in late spring to early summer, the pistillate spikes forming clusters of seeds.
