12. CARYOPHYLLACE^E. 223 



Native. Agrestal, &c. Well known as one of our most 

 universal weeds in gardens, fields, and road sides ; becom- 

 ing rare above the agrarian region, though still occasion- 

 ally met with in spots trodden by cattle or sheep, up to 

 800 or 900 yards. It is conveyed to all parts of the globe, 

 where agricultural processes are canied on, unless some of 

 the hot and dry intertropical countries be exceptions.

Native. Septal and Rupestral. Very scarce above the 

 agrarian region ; but observed in Forfarshire and Aberdeen- 

 shire, between 500 and 700 yards. Probably rare in the 

 North Isles ; Dr. Neill being the only botanist who has re- 

 corded it thence. I call it 'Rupestral,' because it is seen 

 hanging from the crevices of rocks, among the mountains, 

 where hedges are non-existent.
