POLYANDRIA. 327 



CLASS 13. Polyandria. Stamens numerous, inserted 

 into the Receptacle. Orders 7. 



1 . Monogynia. 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, Curt. Mag. 

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

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

 genus Cistus, with its copious but short-lived flowers* 

 some of which (EngL Bot. t. 1321) have irritable 

 stamens ; the splendid aquatic tribe of Nymphtfa y 

 &c., 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 Paonia, t. 1513, va- 

 riable in number of pistils, and Fothergilla alnifolia, 

 an American shrub. 



3 . Trigynia. Delph inlum 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
