 A Polypliyllous Perianth is either equal orunequal : 



Equal, as in Wall-flower, (Cheiranthus) fig 1, 

 pi. 5. 



Unequal, as in Field Gentian, (Gentiana cam- 

 pestris) fig. 2, pi. 5, where the two inner 

 leaves are much smaller than the outer. 



The general form of the Perianth is either 



Erect, as in Soap-wort, (Saponaria) fig. 3, pi. 5. 



Globose, as in Knapweed, (Centaurea) fig. 4. 



Inflated, as in Yellow-rattle, (Rhinanthus) fig. 5.

 plants commonly called Butter-cups) fig. 6.

The Perianth is generally placed below the Ger- 

 men (the name by which the pericarp is called be- 

 fore it grows to maturity,) but is sometimes above 

 it, as in Brookweed, Samolus) fig. 8, and the 

 flowers of the Apple-tree, on the fruit of which it 

 may be generally seen.
