* One of the most extensive orders in the vegetable kingdom, and 
one which botanists have at all times found much difficulty in subdi- 
viding. Jussieu, the originator of the present natural method of bot- 

any. elevated his three divisions of this great tribe to the rank of dis- 
tinct orders; but in view of their close resemblance and intimate re- 
lation, later botanists very justly object to this arrangement. Con- 
sidered as sub-orders, they are quite as philosophic and satisfactory 
as any that have been proposed. In arranging the western species of 
composite, I follow Professors Torrey and Beck in adopting the 
classification of M. Don, which, though it does not differ very essen- 
tially from that of Jussieu, has the advantage of subdividing this 
extensive order into a greater number of natural groups. The 
— Carduacee of Don, are nearly equivalent to. the Cinarocephale of 
Jussieu:—the Cichoracee of both authors are the same. The Corym- 
bifere of Jussieu have by Don been made to constitute several distinct 
sub-orders. Corymbiferz are generally tonic and secernant stimu- 
lant, Cinarocephale tonic and often cathartic, Cichoracez aperient 
and anodyne.
