CHAPTER VIII. 



EXPOSITION OF THE NATURAL SYSTEM OF JUSS1EU. 



The Classes are 15, not distinguished by any par- 

 ticular appellations. One of them is Acotyledonous 

 (90, 91) ; three are Monocotyledonous (88) ; the re- 

 maining- eleven Dicotyledonous (89). 



The Orders are 1 00, distributed in natural series 

 under every Class, and each denned by rather full 

 'definitions, taken, in the first place, from the parts of 

 Fructification (52), and illustrated by secondary cha- 

 racters, founded on any other circumstance. 



The Genera stand, in one or more sections, accord- 

 ing to their respective affinities, and with their 

 Essential Characters (104) under each Order, at the 

 end of which are usually many valuable critical 

 remarks. 



There is at the end a very large assemblage of 

 P lattice incertcB sedis ; Genera not reducible to any 

 of these Orders. These are for. convenience, artifi- 

 cially arranged, by the Corolla (whether monopeta- 

 lous, polypetalous, or wanting), the situation of the 

 Germen, and the number of Styles and Stamens. 

 Many of the Genera have subsequently been reduced 

 to their proper Orders.
