JUSSIEU's NATURAL SYSTEM. 213 



the flowers of which are without petals, and the stamens 

 idiogynous, or in a different flower from the pistils. 



These plants are either monoecious, dioecious, or polygamous. 

 Calyx in each flower of one leaf, or substituted by a scale ; corolla 

 none, but sometimes there are scales, or inner segments of the calyx, 

 assuming the appearance of petals. The barren flowers have 

 stamens inserted into some part of the calyx, or of the scales sup- 

 plying its place, definite, or more rarely indefinite, their filaments 

 either distinct, or sometimes united into a stalk proceeding from the 

 centre of the calyx. Germen of the fertile flowers simple, or some- 

 times several, superior or rarely inferior ; style one or more, or 

 occasionally wanting ; stigma simple or divided ; fruit various in 

 structure, as well as in the number of its cells. 



42. This class is composed of the eight remaining 

 orders of the system ; among which will be found eu- 

 phorbiacea; ', cucurbitacece, passiflorte, myristacecc, and 

 others.

43. We shall here finish our general view of this 

 beautiful and celebrated system, and although but super, 

 ficially explained, it may probably serve as an easy in- 

 troduction to a more detailed study of its ulterioi 

 division. 



The Jussieuan system from its usual agreement with nature, will 

 undoubtedly continue to claim the attention of the botanical world, 

 not only for its superiority to any previous natural arrangement,
