452 ENATION 
Professor Morren considers the adventitious peta- 
lodes as rudiments of so many supplementary flowers, 
axillary to the calyx, and adnate to the corolla; each 
lobe then would, in this view, represent an imperfect 
flower, and the completed catacorolla would be formed 
of a series of confluent flowers of this description. 
But this view involves the assumption of the suppres- 
sion of all the parts of the flower, except the lobes in 
question.

The view here propounded that the lobes in question 
are enations from the true petals, which become con- 
fluent, so as to form the catacorolla, is surely more 
simple, involves no assumptions of suppression of 
parts; and, moreover, is borne out by the examination 
of some flowers, where the production of these adven-
