Carex rariflora, the looseflower alpine sedge, is a species of plant in the sedge family. It is found in the United States in Alaska and Maine, and in Canada in New Brunswick and Nova Scotia.[1] In these regions, it is ranked as an obligate hydrophyte in establishing wetland areas.[2] It prefers wet environments such as open bogs, meadows, seepage slopes, and low-elevation heath tundra.[3] This perennial grass, which can be up to 3 feet tall, has fibrous roots, and holds all perennial organs underground. The leaves are alternate, long, narrow, and simple, with parallel veins.[2] They grow in dense clusters, and the dead leaves are found at the base of the plant.[3] The plant blooms and fruits in the summer. All flowers are monoecious and unisexual, producing a spike inflorescence.[1] All inflorescences are subtended by shorter, proximal bracts.[3]
