For remarks on the nomenclature of Dianthus glaucus, see the next page. 
We have seen no fresh specimens of this variety ; but, judging from the descriptions of it, it would seem to be as 
worthy of specific rank as many forms of Dianthus usually regarded as species. As will be seen from the synonyms cited 
above, Linnaeus accorded it the rank of a species. 
Very rare, and “a doubtful native” (Syme op. cit. 47 (1864)); Surrey, Yorkshire, Edinburghshire. 
Norway, Germany, Denmark, France, central Europe, Russia, Spain ; North America (not indigenous). 
Grassland on dry, sandy soils; local, from Devonshire and Kent northwards to Inverness-shire; 
not known in Ireland. 
Scandinavia, Denmark, Germany, Holland, Belgium, France, central Europe, Russia (central 
and southern), southern Europe (ascending to 1600 m. in the Pyrenees); Asia; North America 
(not indigenous).
