CHfNA ASTER. .•?81 



The young botanist will observe by comparing 

 this flower with the Helianthus, that it agrees by 

 liaving the florets of the disk bisexual, but differs 

 in those of the radius or margin, which are fur- 

 nished with a stigma only, but which are made 

 fertile by the pollen of the centre florets, and 

 hence it is placed in the order called Poli/gamia 

 Supeijlita. The marginal florets of the China 

 Aster are usually ligulate, but we have lately 

 had a beautiful variety introduced, consisting en- 

 tirely of quilled florets.
