 Some of the above localities may belong to G. officinalis, to 

 which C. danica is at least very closely aUied. Mr. Syme 

 places C danica and C. grcenlandiea (our var, cdpina) as a sub- 

 species under G. officinalis ; while he keeps G. anglica as a 

 distinct species. C. danica seldom grows in salt marshes.
