Eriophorum callitrix, commonly known as Arctic cotton, Arctic cottongrass, suputi, or pualunnguat in Inuktitut, is a perennial Arctic plant in the sedge family, Cyperaceae. It is one of the most widespread flowering plants in the northern hemisphere and tundra regions. Upon every stem grows a single round, white and wooly fruit. The seeds are covered in this cottony mass and usually disperse when the wind carries them away. Eriophorum callitrix has narrow, grass-like leaves. Its habitats include tundra and calcareous bogs.[2]
