According to Purs h, fertile plants of this species are sel- 

 dom found north of the Potomac river, though barren ones ex- 

 tend far beyond it. I have followed this author in placino- V. 

 odoratissima of Do nn as a synonym. Mu hlenb erg ve- 

 tains it as a distinct species, to which he annexes the name of 

 Bermudian grafie.
