^ This though nearly allied to the preceding, is a very distinct spci- 

 cies, and easily known from that by its more robust appearance and 

 larger leaves. PursU. 



have adopted this gpecies from Pursh without having sufficient 

 means to determine its accuracy. Yet I have noticed in specimens 

 sent me from our mountains, that those with sterile (radiating) flow- 

 ers have generally a more robust habit, leaves thicker, less acumir 

 pate, and more distinctly ovate. 



^ Grows in the mountains and uppei- country of Carolina and Geor- 

 gia, along the water courses. 



Flowers May — June.
