MONOECIA. 359 



mining any genus, which would be by no means the 

 case if we had them confounded with the mass of the 

 system. Even the species of the same genus, as well 

 as individuals of each species, differ among themselves. 

 How unwise and unscientific then is it, to take as a 

 primary mark of discrimination, what nature has evi- 

 dently made of less consequence here than in any 

 other case ! It is somewhat like attempting a natural 

 system, and founding its primary divisions on the 

 artificial circumstance of number of stamens. 



I proceed to give some illustrations of the Orders 

 in Monotda, 



1 . Monandria. Zanmchellia, Mill. Illmtr. t. 77, and 

 Aegopricon, Plant. Ic. ex Herb. Linn. t. 42, are 

 genuine examples of this Class and Order, having 

 a different structure in the accessory parts of their 

 barren and fertile flowers. Artocarpm, the cele- 

 brated Bread-fruit, may likewise be esteemed so on 

 account of a partial calyx in the barren flowers. 

 The other amentaceous genera may most intelligibly 

 perhaps be referred to the Order Polyandria. Char a 

 is now removed to the first Class in the System ; 

 see EngL Bot. t. 336. 



2. Diandria. Anguria can remain here only till the 

 proposed reformation takes place, having no diffe- 

 rence of structure in its flowers. Lemna, so imper- 

 fectly known when Linnaeus wrote, is now well
