55. LAMIACE^. 259 



North limit in Durham, York, Lancaster. 



Estimate of provinces 6. Estimate of counties 6.

Colonist. Agrestal. Besides the half dozen counties 

 mentioned above, I have a manuscript note for Warwick- 

 shire, but suspect an error on the part of my informant. 

 Lately discovered in Essex, by Mr. E. G. Varenne, ac- 

 cording to Mr. Thomas Bentall (Phytol. iii. 356). The 

 authorities for the other counties may be seen in the New 

 Botanist's Guide ; that for Lancaster (Hudson) requiring 

 verification. Probably introduced by agriculture, and still 

 quite local. Being chiefly, almost exclusively, found in 

 the North of England, it may be deemed nearest to the 

 Scottish type of distribution ; but this is rather attributable 

 to the accident of position, than to the climatal adaptation ; 

 for it is not properly a boreal ^plant in Britain or on the 

 Continent.
