l8o FLOWERS OF FIELD, HILL, AND SWAMP 

 When Don Orsino, in " Twelfth Night," says that the music 



" Came o'er my ear like the sweet south 



That breathes upon a bank of violets, 



Stealing and giving odor," 



he could not have spoken of our American species, which, unlike 

 the English violet, has no scent. But our own is very dear to us. 

 It puts on no airs. It is a humble bit of color. It does not dis- 

 dain to brighten our dooryards or our pasture lands. It seems 

 to like human company, and it always has the same message: 

 " Spring is here." 



Later, cleistogamous blossoms are produced, which are fertil- 

 ized in the bud.
