46. VACCINIACE^. 167 



Range of mean annual temperature 45 — 35. 



Native. Ericetal, Uliginal. According to Aiken, Bing- 

 ley, and GrifBth, this shnib is found in woods near Llannvst, 

 but whether on the Caernarvonshire or Denbighshire side 

 of the stream does not appear ; and it would be desirable 

 to have the habitat confinned by some competent botanist 

 of the present time. It occm's on Teesdale, and thus finds 

 place in the Flora of Yorkshire ; but whether truly within 

 that county I am unprepared to say. If within the boundary 

 of Yorkshire, the provincial estimate must be raised to 7, 

 and the Humber province be no longer excluded. 



705. Vaccinium Vitis-Id^a, Linn. 



Area [1 2 3] * 5 6 7 8 9 10 11 12 13 14 15 16 17 18. 



South limit in Glamorgan, Worcester, Warwick, Notts. 



North limit in the Hebrides, Sutherland. 



Estimate of provinces 14. Estimate of counties 50. 



Latitude 51 — 59. Highland type of distribution. 



A. A. regions. Superagrarian — Superarctic zones. 



Descends to 100 yards, or lower, in Mersey. 



Ascends to 1100 yards, in East Highlands. 



Range of mean annual temperature 47 — 35. 



Native. Ericetal, Rupestral. An example of the High- 

 land type passing into the Scottish. It has been recorded 

 from Somerset (Mr. Dyer, in B. G.), Dorset or Hants 

 (Within 30 miles from Poole : Salter's Bot.), and Kent 

 (Blackstone, cited in B. G.) ; but these authorities are in- 

 sufficient where the species is in itself unlikely to occur. 

 Perhaps it should be considered as descending within the 

 midagrarian zone.
