45. CAMPANULACEiE. 141 



682. Campanula persicifolia, Linn. 



Area (15). 



Alien. In " woods near Cullen, apparently indigenous." 

 (Flo. Scot.) Although widely distributed in ScandinaA-ia, 

 it is to be feared that there is very slight ground for sup- 

 posing this to be a native of Scotland ; nor does it clearly 

 appear whether the plant is still found in the neighbour- 

 hood, or was found there only some years ago. 



683. Wahlenbergia hederacea, Rchbh. 



Area 1 2 3 * 5 6 7 * 9 10 * 12 13. 



South limit in Cornwall, Isle of Wight, Sussex. 



North limit in Renfrew, Isle of Man, York. 



Estimate of provinces 10. Estimate of counties 30. 



Latitude 50 — 56. Atlantic type of distribution. 



Agrarian region. Inferagrarian — Superagrarian zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 300 yards, in the same province. 



Range of mean annual temperature 52 — 46. 



Native. Uliginal. This species does not attain to the 

 superagrarian zone by its latitudinal range ; but since it is 

 stated to occur about Capel Curig (Mr. G. S. Gibson) and 

 in the valleys about Snowdon (Mr. J. E. Bowman, &c.), in 

 North Wales, it would seem to attain that zone by climate 

 and mountain proximity. Very local in the two eastern 

 provinces which are above indicated ; namely, Humber and 

 Thames ; becoming more frequent in the demi-eastern pro- 

 ^-ince of the Channel.
