is reversed. This remark applies particularly to imdi- 
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.
