Eriophorum brachyantherum, the closed-sheath cotton-grass, short-anthered cotton-grass or northland cottonsedge, is a species that is a part of the Cyperaceae or sedge family. It is commonly found in wet areas, such as bogs and cooler climate zones.
Where it grows
The northland cottonsedge has a circumboreal distribution in North America, Europe, and Asia. In the United States it is primarily occurs in Alaska, though it has been recorded from Idaho and Washington as well. In Canada it occurs natively almost country-wide (AB, BC, MB, NL, NT, NU, ON, QC, SK, YT). It prefers to grow in wet areas, and is commonly found in or near bogs, tundra, muskeg, and fens.
Uses
The stem and root of this plant were previously used as food by Native Americans, albeit very seldom. The Native Americans would boil the root or simply eat it raw, and for the stem they would store it or fry it in seal oil. The Yupik people used an extract from the leaves as a medical treatment for a variety of gastrointestinal problems.
