ADHESION. 



is reversed. This I'emark applies particularly to indi- 

 vidual cases; the proportion as regards the genera 

 may not be so large. The explanation of this must 

 of course depend on the circumstances of each par- 

 ticular case ; and it would be wrong to attempt to lay 

 down a general rule, when organogenists have not yet 

 fully decided in what plants the inferior ovary is an 

 axial structure, and in what others the appearance is due 

 to the adhesion of the base of the calyx to the carpels. 

 The list which follows is not intended as a complete 

 one, but it may serve to show what plants are more 

 particularly subject to this anomaly ; the * indicates 

 unusual frequency of occurrence, the ! signifies that 

 the writer has himself seen instances in the plants 

 named. Many of the recorded cases of Synanthy are 

 really cases of adhesion of the inflorescence rather 

 than of the flowers.
