Carex arkansana

Carex arkansana is a tussock-forming species of perennial sedge in the family Cyperaceae. It is native to central parts of the United States.

The sedge has no obvious rhizomes. It has 5 to 60 cm long culms that are 1.4 to 2 mm wide at the base thinning to 0.7 to 0.9 mm at long projections that are wider than they are long. The leaf blade is usually 1 to 1.25 mm in width. The inflorescences are composed of three to six spikes that are 1.5 to 4 cm long and 7 to 12 mm wide.

The species was first described by the botanist Liberty Hyde Bailey in 1896 as a part of the Botanical Gazette. It has one synonym; Carex rosea var. arkansana also described by Bailey.

The plant grows in temperate biomes in the central United States from Illinois in the north to Texas in the south.
