The argument here seems unanswerable, and is in itself more 
clear than the language in which it is interred. It shews that 
bramble-species are really optional even among the special experts. 
Certainly, it does not show that bramble segregates cannot be dis- 
criminated; but it does show that those segregates are not species 
in the strict and usual acceptation of this term. Professor 
Babington writes, page 22, “I believe in the distinctness of 
species, although unable to demonstrate it.” But in whose species 
of Rubi are we to believe? In the two hundred of M. Genevier? 
—In the two score of Professor Babington ?—In the two units, 
Jruticosus and cesius, of Mr. Bentham’s Handbook ?
