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. uniflorum. 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.
