 agency. The Petals are the leaves of the corolla when it is 

 divided to its base. It is then said to be Polypetalous. The 

 corolla is Gamopetalous when the petals are wholly or partly 

 grown together. 



The Calyx and Corolla are spoken of as parted when they 

 are divided nearly to the base. When they are divided about 

 to their middle, they are said to be cleft, or lobed. They are

Wheel-Shaped : when the border spreads out at once from

 (Fig. 42.) 



Campanulate, or Bell-Shaped: when the tube expands

 of the parts. In this form of corolla usually two petals grow
