and leaf it corresponds more closely with the Highland N.

 N. lutea.

Colonist. Agrestal. Locally scattei'ed over a consider- 

 able part of England, on chalk or other calcareous ground; 

 bemg found wild to Durham and Caemarvonshu'e, and re- 

 ported from Northumberland and Flintshire also. I mark 

 this and the other common species, as ' colonists,' under 

 the idea that they owe theu* introduction to agriculture, 

 and might even yet scai'cely keep their hold of British 

 gi-ound without the aid of human labour, in preparing the 

 soil for them. Compared with our more ordinary weeds, 

 the poppies have an exotic character in their large and 

 gaily coloured flowers, and in then- sensibility to fi'ost.
