CHAPTER II 



PISTILLATE FLOWERS AND STAMINATE FLOWERS 



T is self-evident that flowers 

 whollj^ pistillate or wholly 

 staminate run no risk of 

 self -fertilisation ; and nature 

 adopted this simple plan in 

 the case of most of our trees, 

 such as pines, beeches, and 

 birches, whose pollen is car- 

 ried by the wind, and in 

 many plants, as the clematis, 

 Virginia strawberry, the 

 flowering spurge, and Jack- 

 in-the-Pulpit, whose pollen 

 is transported by insects. 

 Trees or plants which bear the 

 pistillate or the staminate flowers 

 separately are said to have the 



"dioecious habit," while those which bear both kinds 



of flowers on one plant follow the 



"monoecious."
