Homomorp'hy and Heteromorphy. 



The adult leaves, or those produced on the vegetative system 

 of the plant, in succession to the cotyledons, may be of the same 

 pattern or they may vary in different stages of the plant's growth, 

 or on different parts of its branches. In that form of Thuya 

 known in gardens as T. Bodmeri, and in that known as Retino- 



suitably be made to others who have studied the anatomy of the leaves from 

 various points of view :
