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

 that Pursh's A. lancifolia is this species, but I have not been able 

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

 mountains in boggy soil, Pennsylvania and Yirginia." Schweinitz 

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

 cuneifolia.^^
