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.
