I know not whether this can be the A. virginicus of LinnssuS ; It is 

 aivnc{l,but the aAvns drop with the slightest touch. It is also not cer- 

 « n whether this or the preceding species is the A. dissitifloruH of 

 Michaux ; his description applies almost equally well to both. I have 

 werefore retained his name to this plant, as the sheath of the former 

 supplrcd both a name and character. *
