Carex leptalea is a species of sedge known by the common names bristly-stalked sedge and flaccid sedge. It is native to much of North America including most of Canada, the Dominican Republic, and the United States.[1] It only grows in wetlands. This sedge produces dense clusters of thin stems up to 70 centimeters tall from a network of branching rhizomes. The thin, deep green leaves are soft, hairless, and sometimes drooping. The inflorescence is up to 16 millimeters long but only 2 to 3 millimeters wide, and is yellow-green in color. There are only a few perigynia on each spikelet, and they are green and veined.
