The plant I once considered as the Eriophorum angustu 

 folium, I am now convinced is nothing more than a variety of 



E. virginicum. I have never seen an Eriophorum from this 

 country resembling my European specimens ot E. angusti- 

 folium. The plant which Bige low lias described under iliifi 

 name appears to be E. poUjstachyon.
