A very singular plant, of which several specimens are in this 

 collection, and which has been nowhere found besides, but on 

 the banks of the Kooskoosky by Lewis, according to Pursh ; 

 and by Dr. Richardson in his expedition between Point Lake 

 and the Arctic Sea. 



The first appearance of this plant resembles so entirely that 

 of an Erigeron, that I had no hesitation, from that circumstance 

 alone, in referring it to this genus ; and indeed, had its leaves 

 been lanceolate and simple, I should have passed it over as a 

 variety of E. unijlorum. My friend Dr. Richardson, however, 

 " has removed it to the genus Cineraria ; though, upon a minute 

 examination of its characters, I can find no circumstance in 

 them to vary from Erigeron.
