Besides these divisions, Linnaeus made a secondary 

 artificial arrangement or subdivision of these Classes 

 into Orders. 



The Orders of the first thirteen Classes are esta- 

 blished upon the number of the Pistilla or Stigmae, and 

 are shewn by a marginal reference in the letter-press 

 accompanying each class. 



The Orders of Class XIV. and XV. are characte- 

 rized by the manner of producing their seed, as shewn 

 in the two plates prefixed to those classes. 



The Orders of Class XVI. XVII. and XVIII. are 

 founded on the number of Stamina which compose 

 them.
