are fufficient to diftingnifh them from all 
Others; but, according to the Linnean iyftem> 
it is neceffary to have recouf fe to the fituation of 
the ftamens, which he defcribes as being united 
into two fets; this claffic character is, however* 
to be traced with difficulty > for what is termed 
one of the fets, confifts of a fmgle filament ; 
and even this obfcure mark does not exift in 
all the genera ; indeed, fo many are deftitute 
of it, that Linneus has, on this failure> founded 
one of the fubdivifions of the fourth order. 
He has, however, efteemed it of fuch effential. 
confequence, that he has excluded from the 
clafs the genus Sophora, w^hich has all the 
characters of the Diadelphia tribe, except that 
of the united filaments ; and ori this fmgle 
deficiency he has feparated it frorri it's natural 
tribe, and placed it according to it's number 
of flarnens, which is ten, in the dafs Decan* 
dria> with the flowers to which it has no 
affinity in any other parts of the fructification. 
The orders, or fcondary divifions of the feven* 
teenth clafs, are founded upon the number of 
■ftamens, without any reference to their union ;
