774. SCROPHULARIA NODOSA, Lhm. 



Area general. 



South limit in Cornwall, Isle of Wight, Kent. 



North limit in Orkney ? Hebrides, Ross. 



Estimate of provinces 18. Estimate of counties 80. 



Latitude 50 — 58 (60). British type of distribution. 



Agrarian region. Inferagrarian— Superagrarian zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 150 yards, in East Lowlands. 



Range of mean annual temperature 52 — 45. 



Native. Sylvestral, Septal, Inundatal. Possibly 80 

 may be rather too high a comital estimate, while the next 

 step in the descending series would likely be too low. The 

 species is omitted from the Floras of Shetland and Orkney, 

 and I did not observe it in Caithness, Sutherland, or West- 

 ern Inverness ; although it cannot be deemed very unlikely 

 to occur in some or all of the three last-named counties; 

 and it may be this present species which was intended 

 under name of " S. aquatica" in Barry's History of 

 Orkney.
