85. cyPERACEiE. 83 



Latitude 50—61. British type of distribution. 



A. A. regions. Inferagrarian — Midarctic zones. 



Descends to the coast level, in North Peninsula. 



Ascends to 1000 yards, in East Highlands. 



Range of mean annual temperature 50 — 37. 



Native. Ericetal. A scarce plant in the four first pro- 

 vinces; increasing in frequency northwards and west- 

 wards ; and becoming common on the Highland moors 

 and mountains. Perhaps the actual number of counties 

 in which it grows may be below 70, but above 60. While 

 in flower or fruit this is a sufficiently conspicuous plant, 

 to render its upper limits less likely to be overlooked, 

 than in the case of more obscure plants. Accordingly, I 

 find considerable uniformity in the altitudes noted for it 

 on different mountains, in the great Grampian range of 

 the East Highlands ; making some allowance for difference 

 of aspect, and other local causes of variation. The usual 

 limit is at 850 or 900 yards. 



1200. Eriophorum angustifolium, Roth. 



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. 



A. A. regions. Inferagrarian — Superarctic zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 1150 yards, in East Highlands. 



Range of mean annual temperature 51 — 35. 



Native. Uhginal, Ericetal. There are 13 counties 

 only in which I am now unable to cite authorities for the 

 occurrence of this species ; and there is scarce a doubt
