Annuals, Biennials, and Perennials.—In the ervets instances 
the results of the examination of the British flora a been confirmed ; 
such is not the case in the comparison we now come to, fir mongst 
Continental herbs Monocarps are found to give Higher ev verage than 
Perennials. In this respect therefore the plants “of the more ect
