 The relationship between llv- 

 drangeads and Saxifrages is ad- 

 mitted by all systematists, who have 

 in genera] united them in the same 



Order. Hie opposite leaves of the form ei tne tendency to a ] 

 "i their radiant male flowers, and n 

 ofler good grounds for separating them. Like Saxifraj .

 mothers, as Hydrangea virens, it i- more than hall 

 curious Japanese genus, has the styles united, and thus 

 roils on the one hand, and to Henslovia on the othei
