The Veronica virginica was many years since proposed as 

 the type ot a new genus by Co Id en,* and afterwards by 

 R afi ne sque, who called it Callistachya. I should have 

 adopted his name, had it not been already applied to a South- 

 American genus. This species is said to be also a native of 

 Japan, which seems hardly probable. " Non, ut Heist er
