 vania; Layton's Station, Fayette Co. (S. W. Knipe, in Herb.

Type, a European specimen in Herb. Linn. I have little doubt

 to find an authentic specimen of it. He says it occurs "on hig] 

 mountains in boggy soil, Pennsylvania and Virginia." Schweinits 

 knew the plant and sent it to A. Brongniart under the name "A. 

 cuneifolia."
