Obs. A variety of this plant is described by Hooker in 

 Scoresby's East Coast of West Greenland, as the S. nitida, 

 a native of high northern latitudes. It was found on the 

 shores of the Arctic Ocean by Dr. Richardson ; at Melville 

 Island, Igloolik, &tc. by Captain Parry and Captain Sabine. 

 The plant collected by Dr. James, resembles almost exactly, 

 specimens in our possession from Melville Island.
