DAISY FLOWERS COOPERATE 
the result is the well-known and widespread yellow 
petals. 
Presently a bee, its attention having been attracted by 
the petal advertisement, stops for lunch. It may run 
its beak into the cup of any one of the hundred florets 
that make up the group. In doing so, it is likely to crawl 
about more or less. As it goes, it shakes off pollen par¬ 
ticles. These find their way into the tiny cups of the 
florets and fertilize them. One bee, visiting the flower 
of any other plant, would fertilize a single cup. Coming 
to see a member of the daisy group, it may shake its 
pollen into a score of them. 
The arrangement of this cooperative lunch counter, 
with scores of cups from which to drink, appeals to many 
insects. The flowers of the daisy people are very popular. 
Thus it happens that they are always fertilized. They 
make many seeds. They have grown very strong in the 
plant world. They are gaining on other groups. The 
scientists believe that this is due to the union of many 
florets into one group and common action in seed-making.
