Aquatic Plants, ^^"atic plants are also pollinated by the 

 wind, as Potamogeton crispus L., a plant 

 growing in ponds and slow running streams. While its 

 leaves are immersed in water tha flowers are produced above. 

 The reddish brown stigmas mature before the anthers of the 

 same flower are open, but when the stigmas are wilting then 

 the perianth of the flower opens, the anthers mature, 

 when the wind blows over the water it carries the pollen with 

 it. Some of it is wasted, but a part of it is almost certain to 

 come in contact with the stigmas c»f younger flowers. 



Herbaceous Pla«ts. Plantain: Common" plantain occurs 

 in all of our door yards and who has 

 not observed the long, slender spike. The flowers are pro- 

 terogynons, the slender style shows before the stamens, when 

 the stamens appear the style is withered. The pollen must 

 therefore move upward. Anemophilous herbaceous plants 

 occur in widely separated orders, as Meadow Rne {Banuncun 

 laceae), Kagweed {Compositae), Hemp ( Urticaceae), etc.
