Moss and Arctic cotton - stock photo

Arctic cotton or Arctic cottongrass, Eriophorum callitrix, is one of the most widespread flowing plants in the northern hemisphere and tundra regions. Upon every stem grows a single round, white and wooly fruit. The seed heads are covered in this cottony mass and usually disperse when the wind carries them away. They also have narrow, grass-like leaves. Photographed near Ilulissat, West Greenland.
