 foundland to Manitoba and the Northwest 

 Territory, south to Florida, Iowa, Utah, 

 and California. Commonly known as fox- 

 tail. Suited to southern ponds of high 

 temperature, and unlike most species will 

 thrive in comparatively soft waters. 

 "Parrot-feather," and introduced species 

 of Myriophyllum will make better growth in 

 sterile ground than the foxtail; otherwise 

 the two have similar characteristics. 



Fig. 3. — Fknwort (Cabomha caroliniana). 

 Foupd in ponds and slow streams, southern 

 Illinois to North Carolina, south to Florida 

 and Texas. Characteristics similar to Cera-

 This plant is shallow-rooted, deriving most 

 of its sustenance from the water. • Will 

 thrive in cold spring water. 



Fig. 4.—Chara fragUlis. A common form of 

 chara. There are many varieties of this 

 species and all are classed very high as 

 food producers and oxygenators. Grows 

 profusely in all limestone waters through- 

 out the United States,
