Fig. 167. A reed swamp, fringing the low shore of a lake or a sluggish stream. The 

 plants are tall and wand-like, and all are monocotyls. Three types are prominent, 

 the reed grasses (the tallest), the cat-tails (at the right), and the bulrushes (a group 

 standing out in deeper water near the middle of the fringing growth). The plaDt 

 in the foreground at the extreme right is the arrow-leaf (Sagittaria), recognized 

 by its characteristic leaves.— After Keener.
