DE CANDOLLE'S SYSTEM. 



Argyranthemum Jacoteifolium. 1. A tubular floret of the disk. 2. A ligulate 

 florel^Tthe ray. 3. Style and stigmas. 4. An anther. 5. An involucrum and 

 Intl receptade, from which the lorets have fallen. 6. R lp e ach^mum cut 

 through vertically, with toothed coronetted pappus. 



The old divisions of this large order are adhered to be- 

 cause they appear more likely to be permanent than the more 

 recent suborders, &c. proposed by De Candolle and others, 

 in which peculiarities in the stigma are chiefly employed. 

 The student who desires to become acquainted with the de- 

 tails of this enormous order, numbering more than 7000 

 species, will consult De Candclle' ( s Prodromus, Vols. V. VI.
