Different forms of Polypetalous Corollas. 



1st. Cruciform (from crux, a cross), con- 

 sisting of four petals of equal size, spreading 

 out in the form of a cross, as the radish, cab- 

 bage, &c. (Fig. 56). 



2d. Caryopliylkus, having five single pe- 

 tals, each terminating in a long claw, en- 

 closed in a tubular calyx, as the pink, 

 (Fig. 57). 



3d. Liliaceous, a corolla with six petals, spreading gradu- 

 ally from the base, so as to exhibit a bell form appearance, as 

 in the tulip and lily. 



4th. Rosaceous, a corolla formed of roundish spreading pe- 

 tals, without claws, or with very short ones, as the rose and 

 apple. 



Fig. 58. 



5th. Papilionaceous, a flower 

 with a banner, two wings, and a 

 keel : the name is derived from 

 the word papilio, 9. butterfly, on 

 account of a supposed resemblance 

 in form, as the pea blossom (Fig. 

 58).* 



If a corolla is not in its form 

 like any of those we have descri- 

 bed, it is said to be anomalous. f

 * It is proper here to observe two important facts connected with the descrip- 

 tions of plants, which are made by references to natural and artificial forms.
