collect a variety of the fpecies arranged under 
thofe divifions, and, by diffecling them, im- 
prefs upon his memory the different characters 
by which the orders are diftinguifhed. The 
dandelion (leontodon), thiftle (carduus), are 
proper flowers for inveftigation ; it will be 
alfo expedient to examine fome violets and 
panfies as examples of the order of fimple 
flowers. There are fome flowers of the fourth 
clafs, Tetrandria, four ftamens, which are 
liable to perplex the young botanift in his 
fearch after compound flowers : in outer ap- 
pearance the mode of inflorefcence in fcabious 
(fcabiofa) nearly refembles that of the com- 
pound flowers, although, on examination, 
there will be found very marked diftin&ions 
between them. The fcabious, and fevera! 
other genera of the fame habits, have their 
four ftamens feparate ; the compound flowers, 
as is feen in the thiftle (carduus), have their 
Jive anthers united in a cylinder : there is alio 
another difference, thcfe flowers of the fourth 
clafs have the florets, of which they are com- 
pofed, attached to the common receptacle by 
a fmall peduncle, or foot-ftalk ; the florets of 
the compound flowers are feffile, or fixed to 
the common receptacle by their bafe, without
