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 plant 
in the foreground at the extreme right is the arrow-leaf (Sagittaria), recognized 
by its characteristic leaves. After KEKNER.
