71. AMENTIFEE^. 395 



Native. Septal, &c. Recorded from about thirty coun- 

 ties only ; but if Neill is correct in reporting its extension 

 northward to the Orkney Isles the estimate of forty coun- 

 ties may eventually be found too low. I am very imper- 

 fectly acquainted with this species myself, and give the 

 area, limits, &c. according to the recorded localities. 



1010. Salix cinerea, Linn. 



Area general ? 



South limit in Cornwall, Isle of Wight, Kent. 



North limit in Shetland, Orkney, Hebrides. 



Estimate of provinces 18. Estimate of counties 82. 



Latitude 50 — 61. British type of distribution. 



Agrarian region. luferagrarian — Superagrarian zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 400 yards, in East Highlands. 



Range of mean annual tempei-ature 52 — 42. 



Native. Septal, &c. I am not prepared to cite posi- 

 tively an authority for the occurrence of this species in the 

 North Highland province, though believing that it was 

 seen there by myself some years ago. On this account I 

 am compelled to make the provincial generality of the area 

 only interrogative instead of positive.
