BIBLIOGRAPHY. 



The following list, while very incomplete, will enable the student to select 

 literature bearing upon the various questions of cross-breeding and hybridiza- 

 tion. The literature of cross-fertijization itself — the means and adaptations 

 by which flowers are fertilized — has been omitted. Those who desire a bibliog- 

 raphy of this subject should consult d'Arcy Thompson's excellent list in 

 Mueller's Fertilization of Flowers. In the present list I have included such 

 references as I have found upon the subject of the immediate influence of 

 pollen upon the resulting fruit.
