The species, divaricata and Sparganophora, are excluded 

 by M. Cassini ; the first under the generic title Epaltes, 

 the second under that of Sparganophorus. 



We have already enumerated the Tribes under which the 

 Compositce are distributed by M. Cassini (see voL 7. fol. 532) . 

 The characters of these divisions have been combined from 

 the following parts of the plant and in the following order 

 of precedence in respect to importance: 1. the style with 

 stigma and its collectors ; 2. the stamens ; 3. the florets ; 

 4. the germen and its appurtenances ; coupled always with 

 the assumption that the parts of those florets that have 

 perfect stamens and pistil are alone available ^r this 

 purpose. The stigma, the most important distinction in 

 the greatest portion of the tribes, is considered by M. 

 Cassini a sole part; the smooth substance which either 

 borders or covers the inner surface of the two branches of 

 the style (stigmatophores) and Is usually confluent at the 

 fork, being alone accounted as such. The variously modified 

 efflorescences that occupy the outer and remaining surface 

 of these branches, or as they have been usually considered 

 by others, separate stigmas, constitute the collectors of M. 

 Cassini, and are so called from gathering the pollen in their 

 ascent along the common axis of the united anthers. 



The generic characters are selected frcmi the seedcrown 

 (pappus), the composition of the common corolla, the ca- 

 lyx, and the receptacle ; recourse being had in complex and 

 intercurrent affinities to the combination of analogies drawn 

 from other parts. 



The above principles are manifestly the result of a com- 

 prehensive investigation conducted with- eminent sagsicity 

 and industry, and will be found in practice to cotnprizef 

 much original resource for the Botanist. The various siec- 

 tions and genera assorted from them {^>p€sr , to us both: na- 

 tural and useful, and such as will be generally adopted ; 

 we trust however without the iantasticS and capiiciously 

 novel phraseology with winch their definitions abound in 

 thePVench.
