PRINCIPLES OF CLASSIFICATION. 37 



96. The insertion of the parts of a Flower, or in 

 other words, the situation of the Germen (59) 

 whether inferior or superior, with regard to the 

 rest, next takes the lead in importance in Jussieu's 

 system ; and in the Dicotyledones the absence or 

 presence, the number or divisions, of the Petals 

 (.55) afford even more leading, if not important, 

 distinctions. 



97. The terms used by Jussieu to indicate the above 

 different insertions apply to the Stamens (58). 

 Thus, 



Stamina hypogyna are inferior, inserted beneath 

 the Germen, fig. 14 and 16. 



Stamina epigyna are inserted above it, fig. 11. 



Stamina perigyna are inserted into the integu- 

 ments of the Flower, which, if simple, is always 

 denominated a Calyx (95) by this author, fig. 

 13; if otherwise, the Stamens are borne either 

 by the Calyx, fig. 19, or the Corolla, fig. 8, 9. 

 But such insertion never takes a lead in his 

 system, unless it be into, what he at least con- 

 siders as, a Calyx. The above terms apply 

 likewise to the Corolla. 



98. Characters derived from proportion, do not enter 

 at all into the principles of Jussieu's Classifica- 

 tion, nor scarcely those founded on number, except 

 so far as whether that of the Stamens or Pistils be 

 definite or indefinite. 



99. This System is confessedly incomplete, as there 

 are numerous, even well-known, Genera (73, 75)
