 river-banks everywhere. 



A daisy like flower about an inch broad, 

 with white, tliree-toothed, neutral rays (i. 

 e., without stamens or pistils) and a yel- 

 low disc, which becomes elongated with 

 age. The small leaves, cut and slashed to 

 absolute formlessness, are remarkable for 

 their disagreeable odor and acrid taste ; used in making 

 a horrible concoction called "chamomile tea." 8-20 

 inches high. Common about dwellings and on road-

 green, stout, and tough stem is fine-hairy. The perfect 

 disc -florets are at first yellowish, but finally graj'- 

 brown ; the 4-6 pistillate rays are white, or rarely crim- 

 son-pink. Fertilized mostly by bees and the smaller 

 butterflies ; chief among the latter is the yellow Colias 

 phiJodice. 1-2 feet high. Common everywhere, by the 

 wayside and in fields • probably native in the w^est, 

 where it is more fine-hairy and less green.
