 present standpoint it does not call for further 

 consideration.

 stamens with their pollen-bearing anthers and 

 the receptive pistil with or without a stigma at 

 its tip, but always having one or more ovules in 

 the egg case at its base are the organs that

HAND-POLLENIZING 



The essence of pollenizing is merely the 

 transfer of pollen from the stamen of one flower 

 to the stigmatic surface at the end or rarely at 

 the side of the pistil of another. 



This is the work that is ordinarily accom-

 hybridizing, of different species.

What is accomplished in each case is the
