LINNiEAN ORDERS. ^©^ 



1. PoLYGAMiA ^q,uALis. Florcts all perfect OF Uni- 

 ted, that is, each furnished with perfect Stamens, a 

 Pistil, and one Seed. 



2. PoLYGAMiA SUPERFL0A. Florcts of the disk with 

 Stamens and Pistil ; those of the radius with Pistil 

 only, but each, of both kinds, forming perfect Seed. 



3. PoLYGAMiA FRUSTRANEA. Florcts of thc disk as 

 in the last ; those of the radius with merely an abor- 

 tive Pistil, or with not even the rudiments of any. 

 This is a bad Order, for reasons hereafter to be ex- 

 plained. 



4. PoLYGAMiA NECEssARiA. Florcts of the disk 

 with Stamens only, those of the radius with Pistils 

 only. 



5. PoLYGAMiA sEGREGATA. Several flowers, either 

 simple or compound, but with united anthers, and 

 with a proper calyx, included in one common calyx. 



Linnaeus has a 6th Order in this Class, named Mo- 

 iwgamia, consisting of simple flowers with united an- 

 thers ; but this I have presumed to disuse, because the 

 union of the anthers is not constant throughout the spe- 

 cies of each genus referred to it, witness Lobelia and 

 Fiola, while on the contrary several detached species in 

 other Classes have united anthers, as in Ge?itia7ia, Engl. 

 Jht. t. 20. These reasons, which show the connection 

 of the anthers of a simple flower to be neither important 

 in nature, nor constant as an artificial character, are con- 

 firmed by the plants of this whole Linuccan Order being 

 natural allies of others in the 5th Class, and totally dis-
