85. CYPERACE^. 89 



Estimate of provinces 17. Estimate of counties 50. 



Latitude 50 — 61. British type of distribvition. 



A. A. regions. Inferagrarian — Midai'ctic zones. 



Descends to tlie coast level, in the Channel. 



Ascends to 950 or 1000 yards, in East Highlands. 



Range of mean annual temperatiu'e 50 — 37. 



Native. Ericetal, Uliginal. Frequent on the northern 

 moors and mountains, but scarce in the 4 or 5 most 

 southerly provinces of England. Whether it really oc- 

 curs at all in the Peninsula, is highly doubtful ; but 

 there is Mr. Borrer's authority for one habitat in the 

 Channel province ; namely, the county of Sussex. The 

 other 16 provinces are sufficiently supported by botanical 

 authorities. 



1205. Carex pulicaris, Linn. 



Area general. 



South limit in Cornwall, Isle of Wight, Kent. 



North limit ui Shetland, Orkney, Hebrides. 



Estimate of provinces 18. Estimate of counties 80. 



Latitude 50 — 61. British type of distribution. 



A. A. regions. Inferagrarian — Midarctic zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 850 yards, in East Highlands. 



Range of mean annual temperature 52 — 39. 



Native. Uliginal, Ericetal. Perhaps the county esti- 

 mate may be slightly too high, although there seems 

 about equal chance that it may be as much too low. 

 Localities are known in nearly 60 counties; and all the 

 rest seem likely enough to produce this species, judging 

 by their geographical position, and character of surface ;
