Rare in bogs. This and a few other sedges, grasses, and 

 aquatic mosses form by their long, interlacing roots the 

 tough sod which covers the surface of the quaking bogs in 

 the northwestern portion of the state. This sedge flowers 

 and fruits here onlv under the most favorable conditions of 

 moisture and temperature. Also a native of northern Europe.
