CALYCIFLOR^. 



This Class includes not only those plants where the Stamens grow from an herbaceous ring:, 

 which might be considered as belonging to the Calyx— the Fenrjijna of Jussieu, — but also most 

 of the Epigyna of that author ; the theory supposing that a Calyx exists, but attached to the 

 Germen. In the fii-st 24 orders here admitted (with the exception of the Cucurhitacecp) the 

 Petals are separate; the last 11 are mouopetalous. The Zor«»i/<«C(?(» are uncertain. Various altera- 

 tions and, perhaps, some improvements, have been made by late writers in the limits and distribu- 

 tion of this Class, but I have thought better to adhere to an arrangement which has been applied to a 

 general work on Botany, than to choose whose I would foUow among the authors of limited Moras.
