Hab. Canada, Michaux! ; Hudson's Bay Country, Dr. 

 Richardson; Island of Sitcha, Russian America, Mcrtcn^. 



Obs. I have seen no North American specimens of this 

 plant except those in Michaux's herbarium, which I did not 

 examine with sufficient accuracy for determining whether they 

 are identical with the S. syJvaiicus of Europe.

Har. Pine barrens South Carolina, Elliott.! May — June. 



Obs. a well-marked species, which, however, does not 

 appear to be widely diffused. My specimen of it was received 

 from Mr. Elliott, who also probably supplied Dr. Muhlenberg 

 v/hh the plant, which he described under the name of S. Vmea- 

 ius. It has not hitherto been found except in the state of South 

 Carolina.
