The sedge has no obvious rhizomes. It has long culms that are wide at the base thinning to at long projections that are wider than they are long. The leaf blade is usually in width. The inflorescences are composed of three to six spikes that are long and wide.[2]
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.[3]
The plant grows in temperate biomes in the central United States from Illinois in the north to Texas in the south.[1]
