CHAPTER III. 



DICOTYLEDONS. 



THALAMIFLOR^E. 



IN the preceding chapters I have endeavoured to give 

 a general sketch of the relations existing between 

 flowers and insects. I shall now proceed to de- 

 scribe particular instances more in detail, following in 

 general the classification adopted in Mr. Bentham's 

 admirable " Handbook of the British Flora," from 

 which also many of my facts and illustrations have 

 been borrowed. I propose to go through the English 

 Flora, in the order of Mr. Bentham's work, calling at- 

 tention to those facts, bearing on our present subject, 

 which strike me as most interesting. The present 

 chapter is devoted to the thalamifloral division of the 

 Dicotyledons.
