XLII. THE PITCHER PLANT. 



Description. In peat bogs and fresh marshes through-

 similar, except perhaps in color. The species most generally 

 accessible is delineated in Fig. XLII.

 plants is acaulescent, with perennial fibrous roots, leaves 



Heather-peat. The. Heather sprays and blossoms are eaten by grouse and by sheep
