An Ingenius Mechanism 



The stigma of the iris has a little lip under the unique 

 petaloid pistils, adjusted in just the right way to scoop the 

 pollen off the back of a bee as it enters the flower, or from the head of 

 a humming-bird. The bee or humming-bird will come in con- 

 tact with the pollen of this flower only after it has passed 

 the pistil, and the protecting shelf prevents the de- 

 posit of pollen as the insect or bird leaves 

 the flower. It is a most ingenius and 

 interesting arrangement.
