All the Vegetables in Great Britain are divisible, according 
to the System of Linnazus, into twenty-four Clafses. ‘These 
have, of late, been reduced to nineteen, as will be more, parti- 
cularly noticed hereafter,  —-_- nas Sth evohatt 
The characters of the CLassrs are taken either from the 
number, the length, the connection, or the situation of the Sva- 
MENS; but those founded upon the difference of situation, are 
now given up; the Genera and Species formerly so arranged, 
being now dispersed through the other Clafes, according ta 
the number of their Stamens, ~ OAS hits “elt = 
'- The characters of the OrpERS are most frequently taken 
from the number of the Pistits; but sometimes from some 
other circumstances, either of the Stamens or Pistils, as will 
be noticed in the proper place, | foal 
The ¢/sential characters or marks of the Genera, are taken 
from some particulats in the flower, before unnoticed ; but 
"generic descriptions are designed to contain an account of all _ 
the most obvious appearances in every part of the flower... e. .
