Fig. 120 (110). 



White Sweet Clover. Melilotus alba Desv. 

 Usually biennial, erect, smooth 90-300 cm . 

 high; leaflets three, serrate, varying much in 

 width, 10-20 mm. long, not twisted. 



Somewhat extensively sown as a bee plant 

 along highways of the state. Considerably 

 resembling alfalfa, but may be distinguished 

 by smelling of the crumpled leaves, those of 

 Melilotus resembling the odor of the tonka bean. 

 Offensive to cattle, which may be educated to 

 eat it. Valuable to plow under for enriching 

 the land. Seeds u?ed to adulterate those of 

 Alfalfa. Introduced from Europe.

Yellow Sweet Clover. Melilotus officinalis 

 (L.) Lam. Resembles the former; flowers 

 yellow; thriving on moist clay soil, not much 

 of a weed in Michigan.
