As this pink is so commonly cultivated, it has established itself 



and become more or less naturalized in various localities in 



different countries. Like 7). Gar yophyllus, it is only very locally 



distributed, and is recorded in many floras not as an indigenous 



species, but as one that having been long established has become 



quite naturalized.

b. glaucus, JBlocJei, in Oesterr. Pot. Zeitschr. 1884, p. 250. 



This glaucous variety forms the connecting link between the 

 two species. Linnaeus distinguishes the two by their petals. 

 Of this species he writes: — "affinitatem hujus sumraam cum 

 prrccedente docet petalorum faux ; petala magis oblonga, divisa 

 et lacera ultra medium disci (illi vero tantum rnultifida), basi 

 macula livida acuta, pilis purpurascentibus adspersa." — Sp. PL
