the Floras of Glasgow and Berwick on Tweed, it is recorded 

 in terms which apparently intend to deny its nativity, al- 

 though ambiguously. The places in which it has been 

 seen by myself, were all liable to suspicion ; and yet I 

 must admit that some of them would have passed un- 

 questioned and readily, as true localities for any native 

 shrub otherwise unsuspected.

Estimate of provinces I. Estimate of counties 2. 



Latitude 52 — 53. Local or Germanic type of distribution. 



Agrarian region. Inferagrarian zone. 



Descends to the coast level, in the Ouse province. 



Ascends to 50 yards, more or less, in same province.

Native. Glareal ? A very local plant; and one whose 

 situations of growth are variously stated in respect of hu- 

 midity, as " moist, barren, sandy, heaths," — "barren sandy 

 heaths," — " driest spots," — " gravel walks," — &c. In 

 Salter's list of plants around Poole, in Dorsetshire, this is 

 marked as " very common ; " but that list being the only 

 authority for it in the province of Channel, 1 fear some error. 

 Through cultivation as a botanical curiosity, it has become 

 naturalized in places near London ; but I know not of any 

 truly native habitat in the province of Thames. The 

 British Flora says, " in various parts of England."
