NATURAL ARRANGEMENT, 
107S 
of the artichoke, the cardoon, and others, have the power of curdling milk. The arrangement of Compositas 
is attended with extreme difficulty ; the greatest progress that has yet been made in reducing them to order 
has been with M. Cassini, by whom they are called Synantherece : but unfortunately, the remarks of that 
learned botanist are so scattered and unconnected, that the public has hitherto been able to derive little benefit 
from his labors. His general arrangement is here adopted, but for the reasons now given, his genera have not 
been enquired after, as, until they shall have been more completely systematized, the adoption of them would 
necessarily be full of errors, which would only add to the confusion that already too extensively exists. Those 
who wish to make themselves masters of this very interesting and difficult branch of systematic botany, should 
consult the Opuscules phytologiques of M. Cassini, and Mr. Brown's elaborate essay on the structure of 
Compositaf, in the Transactions of the Linnean Society.
