METAMOHPHY. 



The following list will serve to show what plants 

 are most subject to this anomaly. It is difficult to 

 draw any accurate inference from this enumeration, 

 but attention may be called to the frequency of this 

 occurrence in certain plants, such as the Sempervimim^ 

 the wallflower, the poppy, and the heath. Why these 

 plants should specially be subject to these changes 

 cannot be at present stated. 



By the student of animal physiology such a change 

 as above described equivalent to the substitution of 

 an ovary or a uterus for a testis would be looked 

 on as next to impossible; the simpler and less spe- 

 ciahsed structure of plants renders such a change in 

 them far more easy of comprehension.
