A knowledge of the Orders may be very easily attained, by 

 observing that, 



In the class Didynamia, they depend upon the seeas having a 



seed-vessel, or not 



Tetradynamia, upon the shape of the seed-vessel. 

 Syngenesia, upon the structure of the florets. 

 Cryptogamia, upon the natural assemblages of plants resem- 

 bling each other. 



And that in all the other classes, excepting Monadelphia, Dia- 

 delphia, and Pnlvrulelphia, they depend upon the number of pis- 

 tils only, la determining the number of pistils, count the styles, 

 as they appear at their bottom part, or base ; but if the summits 

 are not supported upon styles, then count the summits.
