feen ; and though apparently feparated at the 
top they will be found firmly united at the 
bafe. The orders are characterifed from the 
number of ftamens found in each flower ; the 
geranium and mallow, having many ftamens/ 
are arranged in the order Polyandria. The 
form of the papilionaceous, or butterfly, tribe 
of plants is fo evidently different from that 
of all others, that no additional mark is rer 
quifite to diftinguifti them ; but in referring 
thefe flowers to the clafles eftabliflied by Lin- 
neus, the fyftcmatic character of Diadelphia, 
two brotherhoods, muft be examined: this 
he has made to depend upon the union of 
the ftamens into two fets, which would lead 
the botanical ftudent to expect a more equal 
divifion of the filaments than does in reality 
exift ; the pea (pifum), having a large flower, 
will give a juft idea of the true pofition of 
the ftamens ; thefe are ten in number, nine 
of which are feparated from the tenth, and 
clofely united at the bafc. On this feparation 
of the tenth filament Linneus has founded 
his claffical character, not, however, unap- 
prifed of it's deficiency, as in feveral genera 
he fyas made the connexion of all the ftamens 
the mark by which he collected them under q. 
fubdivifion
