MADDER FAMILY 133 



Quaker Ladies. Innocence is a charming and 

 appropriate name but I can see no reason why the 

 plant should ever have been called the Dwarf Pink 

 or American Daisy, though the sweetness of its 

 delicate perfume is well suggested by the name 

 " Baby's Breath." 



The Bluets are of as much interest to the bot- 

 anist as to the lover of beautiful landscapes, for 

 this is a dimorphous or two- formed flower : in 

 one form the style of the pistil is long, bringing 

 the stigma to the mouth of the corolla while the 

 stamens are inserted towards the base of the tube ; 

 in the other form the pistil is short while the 

 stamens are inserted near the mouth of the tube. 

 The first is called the long-styled blossom and the 

 second the short-styled. 



Nectar is secreted in the base of the flower cup 

 and the blossoms are freely visited by small bees 

 and butterflies : cross-pollination is brought about 

 by these visits because the pollen from the short- 

 styled flower is carried to the stigma of the 

 long-styled flower, while the pollen from the long- 

 styled flower is carried to the stigma of the 

 short-styled one. An examination of the stigmas 

 of the short-styled flowers will show how this 

 happens. 



The Bluets are very sensitive to atmospheric 

 conditions. At night and in rainy weather the 

 blossoms turn down, to become erect again when 

 sunshine appears.
