fourth class containing collective fruits, as has been done by 
more carpologists than one. While the true aggregate fruit 
is produced by the ovaries of a single flower, a collective 
fruit, if aggregate, is produced by the ovaries of many flowers ; 
a most important difference. As the pericarp is necessarily 
much affected by the calyx when the two adhere so as to form 
a single body, it is indispensable, if a clear idea is to be 
attached to the genera of carpology, that inferior or superior 
fruits should not be confounded under the same name : for 
this reason I have in all cases founded a distinction upon that 
character. 
In order to facilitate the knowledge of the limits of the 
genera of carpology, the following analytical table will be 
found convenient for reference. It is succeeded by the cha- 
racters of the genera in as much detail as is necessary for the 
perfect understanding of their application.
