On this account Linneus has rejected the di- 
mensions of the parts, except relatively, one to 
the other ; place of growth alfo is too uncertain 
to be admitted as a decided character: but all 
thefe circumftances of Smell, tafte, colour* 
Size, and Situation, are noted after the Specific 
characters in the Species Plantarurn, and have 
their uSe, if taken in aid of the more decided 
marks of difcrimination. Linneus efteemed 
the nectaries of greater importance in deter- 
mining the genera, than almoll any other 
part ; and, by the ufe he has made of them, 
has eftabliflied their conSequence, although fo 
much neglected and overlooked before his 
time that they had not even a name. In the 
clafs Monadelphia, one-brotherhood, the or- 
ders depend on the number of ftamens ; and 
the genera contained in thofe divifions are 
again Separated by their number of piftils. 
But although this is the leading character, it 
is by no means Sufficient to diftinguifli the 
families from each other. The manner of 
growth, of the feeds, or the veffel by which 
they are contained, with the number of divi- 
fions of the calyx, are frequently had recourfe 
to in the discriminations oS the genera. From
