LINNJEAN 



2. POLYGAMIA SUPERELUA. Florets 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. Florets of the disk as 

 in the last; those of the radius with merely an 

 abortive Pistil, or with not even the rudiments of 

 any. This is a bad Order, for reasons hereafter to 

 be explained. 



4. POLYGAMIA NECESSARIA. Florets 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 sixth Order in this Class, named 

 Monogamia, consisting of simple flowers with united 

 anthers; but this I have presumed to disuse, because 

 the union of the anthers is not constant throughout 

 the species of each genus referred to it, witness 

 Lobelia and Viola, while on the contrary several 

 detached species in other Classes have united anthers, 

 as in Gentiana, Engl. Bot. 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 confirmed by the plants 

 of this whole Linnsean Order being natural allies 

 of others in the fifth Class, and totally discordant, 

 in every point, from the compound syngenesious 

 flowers.
