There is something especially fascinatittg about plants that grow 

 in the water. They are generally odd and striking. They are 

 perhaps just out of reach, and if you cannot hire a barefooted 

 boy, you must get a row-boat in order to secure the treasures. They 

 look so cool and clean, and rest so quietly upon the lake s placid sur- 

 face ! The bright colors of the flowers mingle harinoniously with 

 their large, undivided, or else finely cut, seaweed-like leaves — for 

 our aquatic foliage is apt to run to one of these extremes. 



We have not many purely aquatic plants. Sometimes the arrow- 

 head and others which have been grouped with swamp plants be- 

 come aquatic, growing quite i7t water, and the water-aricm, which 

 is placed in this chapter, sometitnes takes root in muddy marshes. 

 So the dividing-line between this and Chapter II. is at times indis- 

 tinct.
