TABLE or CLASSIFICATION. 



12. ICOSANDUIA. 



This class con- 

 sists of herma- 

 phrodite plants, 

 with twenty or 

 more stamens fix- 

 ed in the calyx. They 

 produce our most esteem- 

 ed fruits; and no poison- 

 ous fruit has yet been 

 found where the parts of 

 the flower correspond 

 with the characters oi thia 



13. POLYANDIUA. 



The plants be- 

 longing to this 

 class are herma- 

 plu-odite, and 

 have twenty or 

 more stamens fixed in the * 

 receptacle. The situation 

 or insertion of the stamens 

 constitutes the essential 

 and characteristic distinc- 

 tion between the twelfth 

 and thirteenth classes.

2 Angiospennia 



with four stii- . 

 mens, t\vo longer 

 than the other 

 tivo, and one pistil. Tlie I 

 orders are formed upon < 

 the presence or absence of j 

 a covering to the seeds. ' 

 The flowers in the first 

 order are all ringent; in 

 the second order they are 

 most frequenlly person- 

 ate, or resupiuate. 



15. TETRADYNAMIA. 



Plants of six 

 stamens, four ' 

 long and two 

 short, and one ( 

 pistil, wliich 

 turns into a « 

 tvvo-valved pericarp, call- ( ' S'liculosa 

 edaSiliqua; someofthese J 

 pericaros are long, and re- j 

 tain the name siliqua: f „ o-.- 

 othersare short, round, or ^ oiuq»osa 

 flat, and receive the name 

 of silicle, and upon this 

 distinction of their seed- 

 pods the orders are form- 

 ed.

The plants in 

 this class liave 

 their stamens in 

 two sets, of

 of their stamens, and the 

 other genera have one sta- I 3 Decandria

 of the pistil.

The plants of 

 this class are 

 hermaplirodite, 

 nnd their sta- 

 mens are miited into tlu-ee I
