180 51. CONVOLVULACEyE. 



Native. Glareal, Agrestal, Septal. Apparently quite 

 local in Scotland, except in the north-eastern counties. 

 Orkney, on the authority of Dr. Neill, is the only habitat 

 I am aware of in Scotland, to the north and west of Moray, 

 Stirling, and Renfrew. Abundant in the south of England. 

 Thus, by area and latitudinal range, it comes nearest the 

 British or general type ; while by the wide difference in 

 comparative frequency in the southern and northern pro- 

 vinces, it corresponds closely with the English type of 

 distribution. 



730. Convolvulus sepium, Linn. 



Area 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16. 



South limit in Cornwall, Isle of Wight, Kent. 



North limit in Moray, Forfar, Argyle. 



Estimate of provinces 16. Estimate of counties 60. 



Latitude 50 — 58. English type of distribution. 



Agrarian region. Inferagrarian — Superagrarian zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 100 or 200 yards, in England. 



Range of mean annual temperature 52 — 47. 



Native. Septal, Paludal. Abundant in the southern 

 provinces of England ; very local in Scotland, and possibly 

 not truly native beyond the latitudinal parallel of 56 or 57. 

 Said to be frequent about Glasgow (Flo. Glott.), rather 

 rare about Edinburgh (Cat. B. S. Ed.), absent from the 

 neighbourhood of Aberdeen (Flo. Abred.), and reported 

 from single localities only in the Floras of Forfar and Mo- 

 ray. Thus, it approximates more closely to the English 

 or southern type of distribution, than the rather commoner 

 species, C. arvensis.
