position, and in that way secure protection of their 
tender parts. The position is also an advantage to 
the growing flowers above ground. The green 
covering acts as an umbrella, keeping too much 
moisture away from the delicate parts. 
Why do the flower-stalks get longer and thinner 
as the flowers mature ? Because the plant is drawn 
up to the light, and in this way gets above sur- 
rounding vegetation, thus securing air and the 
attentions of insects. 
Why do the flower-heads droop after holding them- 
selves up for a time? Because the flowers have 
done a goodly part of their work. The male pollen 
has reached the female organs, and the seeds in the 
ovaries have been fertilized—that is, made capable 
of producing new plants. The plant is exhausted 
by this heavy work, and hangs its head like a tired 
child. But while the head is hanging the seeds are 
maturing, and they are protected while being 
formed by the natural umbrella made by the green 
receptacle. 
Why do the heads hold themselves up again after 
the seeds are formed ? Because they desire their 
seeds to be scattered to the best advantage. They 
hold them up to the wind, which loosens them and 
carries them away. The seeds have what is called 
a “‘ pappus,”’ which enables them to be wafted in the 
breezes like tiny parachutes. When there is a lull 
in the wind the seeds descend to earth, where they 
may grow if left undisturbed. 
Why does the Coltsfoot have its seeds scattered 
in this way ? Because the plants would be too 
crowded if the seeds were all planted near the
