was that in every case the first recognizable character was that of 
inferior or superior ovary, and a most simple grouping on that 
basis was apparent. 
e appearance of this character in development can be told 
in a few words. In the case of an inferior ovary, the protuber- 
ance which is to develop into the flower is arrested in its axial 
development, grows peripherally into a collar, and soon pe 
appears an external constriction, distinguishing the nascent flora 
envelopes above from the ovary below. The character of an 
external constriction is always the most readily recognized, and 
is as sure a mark of an inferior ovary as the harder seen arrest 
of axial development. ; 
n the case of a superior ovary, the axial development 1s con 
tinued, and there is'no external constriction. All this is per- 
fectly clear before there is a possible recognition of any other 
oral character.
