almost all parts of their bodies the yellow pollen 

 adhered. That the beetles enjoyed the nectar 

 there was no doubt, but to get it they had to 

 undergo a rough-and-tumble experience, whether 

 they liked it or not. And this was the barberry's 

 device for getting its pollen conveyed to other 

 blooms, and for receiving pollen itself from other 

 stamens for the pollination of its own ovary. 

 Thus cross-pollination is insured, and that means 

 fertile seed and the strengthening of its race.
