considered intermediate between the Germanic and Bri- 

 tish ; failing to reach the generality of the latter through 

 its apj)arent absence from the western and noi-theni coasts 

 of Scotland. 



1275. Pkleum asperum, Jacq. 



Area [1] * 8 4 [5]. 



South limit in Somerset ? Gloucester ? Oxford ? 



North limit in Cambridge ? Bedford ? 



Estimate of provinces 2. Estimate of counties 3. 



Latitude 51 — 53. Local (Germ.) type of distribution. 



Agrarian region. Inferagrarian zone. 



Descends to the coast level. 



Ascends to 50 yards, more or less. 



Range of mean annual temperature, say 49. 



Native ? Glareal. A very rare grass, or one almost 

 unaccountably overlooked by the botanists of the present 

 day. The five counties above mentioned have been re- 

 corded as producing it ; but in that of Cambridge it would 

 appear (Bot. Guide) to have been repeatedly soixght with- 

 out success ; it is, however, included in Henslow's Cata- 

 logue. One specimen only is preserved in my British 

 herbarium, and unfortunately the label of that single 

 specimen has been lost. If still existent in English 

 stations, this species may perhaps have been j)assed by 

 as the P. arenarium ; and it would be worth while care- 

 fully to examine any alleged inland localities for the 

 latter, on the chance of finding P. asperum with it, or 

 instead of it. For the present, the alleged counties in the 

 Thames and Ouse provinces are retained; the others 

 being rejected.
