POLYANDRIA. 327 



Class 13. Polijandria. Stamens numerous, inserted 

 into the Receptacle. Orders 7. 



1 . Monogynla. The genera of this order are artificially 

 distributed according to the number of their petals, 

 but not so arranged in the body of the system. 

 They form a numerous and various assemblage of 

 handsome plants, but many are of a suspected 

 quality. Among them are the Poppy, the Caper- 

 shrub, the Sanguinaria canadensis y Curt. Mag, 

 t. 162, remarkable for its orange juice, like our 

 Celandine, Engl, Bot. t. 1581 ; also the beautiful 

 genus Cist us, with its copious but short-lived flowers, 

 some of which {Engl. Bot. t. 1321) have irritable 

 stamens ; the splendid aquatic tribe of NymphcEa, 

 Sec, t. 159, 160, 2292. But the precious Nutmeg 

 and the Tea* are perhaps erroneously placed here 

 by Linnaeus, as well as the Clove; while on the 

 other hand Cleome more properly belongs to this 

 part of the system than to the fifteenth Class. 



2. Digynia has principally the P(Eonia^ t. 1513, va- 

 riable in number of pistils, and Fothergilla alnifolia, 

 an American shrub. 



3 . Trigynia, Delph inium the Larkspur, and Aconitum 

 the Monk's hood^ two variable and uncertain genera 

 as to number of pistils. 



4. Tetragynia. Tetracera ought, by its name, to 

 have constantly four pistils, but the rest of this order
