Hichardson; Island of Sitcha, Russian America, Mertcns. 
Obs. I have seen no North American specimens of this

examine with sufficient accuracy for determining whether they 
are identical with the S. sylvoAicus 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 
with the plant, which he described under the name of S. linea- 
lus. It has not hitherto been found except in the state of South 
Carolina.
