Native. Sylvestral. In almost all the counties of the 

 first five or six provinces ; local or wanting in the rest of 

 the English provinces. I am indebted to Mr. Storey for a 

 Northumbrian specimen, collected by the Rev. J. C. Bigg, 

 in a plantation at Linden, near Alnwick ; and Mr. Moore 

 reports it as lately discovered in Yorkshire, in a copse be- 

 tween Bilton and Wighill Park. For its occurrence in the 

 counties more southward, as Derby, Montgomery, &c., 

 authorities may be seen in the New Botanist's Guide. 



Euphorbia Characias, Linn. 



Area [5]. 



Incognit. Euphorbia amygdaloides appears to have 

 been occasionally mistaken for this species, which has 

 never been found wild in England ; and which, it is said, 

 would not bear the climate of this country without protec- 

 tion in winter. It has been reported to occur in the coun- 

 ties of Worcester and Stafford, and by several different 

 observers.
