CONSPECTUS OF THE ORDERS CONTAINED IN 



THE SECOND VOLUME. 



Class L DICOTYLEDONS. 



Subclass L POLYPETAL.f:. 



(Continued from YoL I. p. 4.) 



Series III. Calyciflor/E.— Stamens and petals usually inserted on the 

 margin of a thin disk lining the base or the whole of the calyx-tube, and free 

 from the ovary unless the calyx-tube is also adnata to it. Stamens definite 

 or indefinite. Ovary either free and superior, or enclosed in the calyx-tube, 

 or inferior and adnate to the calyx-tube. 



(In 3Iimosece and a few genera of Papilionacece and CmafjjmieiB, as well as in isolated 

 genera of Saxifragea; and some other Orders, the stamen-LcariDg disk is reduced to a nar- 

 row ring or disappears altogether. The distinction between Cahjciflone and Thai amiilor(S 

 is therefore general only, not absolute.) 



(The whole of the Calyclfiom not having yet been gone through, either for the present 



work or for our ' Genera riantarnra/ the subdivision of the Series into Alliances is, for the 

 present, deferred.)
