The following is a tabular view of the orders that have to be 

 arranged in the classes thus limited. 



It is assumed that each class divides into two series ; the 

 one having albumen as a necessary part of the structure, the 

 other either wholly or almost destitute of that substance (see 

 652). 



I have also adopted the principles before spoken of as ap- 

 pearing well suited to the construction of subordinate series 

 (see 655) ; and, with reference to this, the following terms 

 are employed in the sense now assigned to them. 



1 . Consolidated ; when the floral envelopes are united both 

 with each other and the stamens, and with the ovary. 



2. Separated; when the floral envelopes and stamens are 

 united with each other, but the ovary is consolidated and free. 



3. Adherent ; when the petals and sepals adhere to each other 

 and the stamens and ovary, but have their parts disunited. 



4. Disunited ; when the sepals and petals adhere to each 

 other and the stamens ; but have their parts disunited, and do 

 not adhere to the consolidated ovary. 



5. Dissolved; when the sepals and petals are distinct from 

 the stamens, and also from the ovary, whose carpels are dis- 

 united either wholly or by the styles. 



These five gradations seem to comprehend all the material 

 degrees of union, from complete consolidation, as in Composite, 

 to complete separation, as in Rammculacese.
