(Carex nebrascensis)
Carex nebrascensis produces upright, angled, spongy stems up to about 90 centimeters tall. The waxy, bluish leaves form tufts around the base of each stem. The root system is a very dense network of rhizomes. The inflorescence includes a few narrow staminate spikes above some wider pistillate spikes on short peduncles. The fruit is covered in a tough, slightly inflated sac called a perigynium which sometimes has a pattern of red spotting.
