Hab. Canada. Willd. herb, — The specimens originate probably from Muhlenberg, but lately bota- 

 nists seem not to have met with it in British North America. S, paniculata, EH., is very near, and it dif- 

 fers especially by a very short calyx and white flowers, both characters of not much value in Sabbatia: be- 

 sides, however, the filaments of the latter and the leaves are shorter: the inferior ones more blunt.""
