212. Protection of FoUen from Rain. — Pollen is very gen- 

 erally protected from being soaked and spoiled by rain or dew 

 either by the natural position of the flower preventing rain 

 from entering, as in the case with most gamopetalous, nodding 

 flowers, or by changes in the position of the flower, and by its 

 opening in sunny weather and closing at night or during 



tions at the right. Mull, stands for Muller's Fertilization of Flowers ; Lubbock,
