with the Channel province. It appears also to occui*, 

 more or less temporarily, in the counties of Warwick, 

 Chester, Lancaster, and York. But those of Salop, Gla- 

 morgan, Denbigh, Nottingham, Durham, Northumberland, 

 Cumberland, and Edinburgh are little to be relied upon ; 

 the species having been mistaken, or having appeared 

 there only as an occasional straggler introduced by agri- 

 culture.

Colonist ? Agrestal ? Distinguished from A. Spica- 

 venti, only three or four years ago in this country ; and 

 known as yet from one habitat only, though one extend- 

 ing into two counties ; namely, the neighbourhood of 

 Thetford, in Norfolk. Perhaps it will be fomid also in 

 other localities for A. Spica-venti, as the two are said to 

 grow intermingled about Thetford. Not having seen the 

 station, I am unable to say from the unprecise words of 

 other botanists, whether the terms " colonist " and " agres- 

 tal " correctly describe the condition and situation of A. 

 interrupta.
