Exercise 34. — IdentiflcoMon of Seeds of Grasses and Legumes. 



Purpose: To familiarize students with common farm seeds. 



Directions: After students have become familiar with the seeds 

 of the grasses suggested in Exercise 33, mixtures of the seeds should 

 be made and the students required to separate them. The same re- 

 quirements may be made with regard to seeds of the following 

 legumes: Alfalfa, sweet clover, red clover, alsike, white clover, bur 

 clover, Japan clover, crimson clover, and yellow trefoil. It will be 

 necessary to give special attention to seeds which look alike, such as 

 alfalfa and sweet clover. A hand lens will be found useful in this 

 work. 



Record and report: Drawings of the seed magnified about 10 

 diameters should accompany a brief clescri'ption of each variety.
