Estimate of provinces 8. Estimate of counties 20. 



Latitude 50 — 55. Gennanic (.'') type of distribution. 



Agrarian region. Inferagi"arian — Midagrarian zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 100 or 200 yards, in England. 



Range of mean annual temperature 50 — 48. 



Native. Pascual. Being frequently sown by agiicul- 

 turists, this species has become naturalized, to some degree, 

 in habitats in which it is not a native. As a truly indi- 

 genous production, it is found chiefly or exclusively on the 

 chalk and limestone tracts of the eastern provinces, but 

 extending also into the sub-western province of Sevems and 

 the county of Somerset, in the province of the Peninsula. 

 For the other western provinces I find only one locality, in 

 Anglesea, and hesitate to receive this far western ' outlier ' 

 until confii'med. The type of distribution appears to be 

 intermediate between the English and Germanic ; and 

 should this plant be really native in Anglesea, we must 

 prefer the former type for it.
