CLASS 11. DODECANDRIA. 



(Containing Plants with more than Ten, and less than Twenty 

 Stamens.) 



A small class, to which are referred only eight British plants,

 Milk-wort was placed here, which is now carried to the twenty-

 is a rare British plant, which belongs to the first order of this 

 class. Of interesting foreign plants, belonging to this class, we 

 may find examples in Bocconia, the Mangrove tree, the Man- 

 gosteen, the Snowdrop tree, and the Canella a well-known 

 medical plant.
