Latitude 50—58. British type of distribution. 



Agrarian region. Inferagrarian — Superagrarian zones. 



Descends to the coast level, in the Peninsula. 



Ascends to 300 or 350 yards, in the East Highlands. . 



Range of mean annual temperature 52 — 44. 



Native. Glareal. Being omitted from the lists of spe- 

 cies known in Shetland, Orkney, Hebiides, Sutheriand 

 and Caithness, it would seem that this common English 

 plant becomes very scarce in the extreme north of Britain; 

 though said to be frequent in Moray, and common about 

 Aberdeen. The county census is estimated on the pre- 

 sumption that the plant will really grow everywhere, ex- 

 cept in Orkney and Shetland, which still do not appear 

 very unlikely habitats for a species which grows at above 

 300 yards of elevation in the valleys of the Grampians.

Native. Glareal. A local plant, the range of which 

 has been unduly extended by mistaking for it examples of 

 S. annuus. I have myself seen S. perennis only from the 

 counties of Suffolk (Mr. S. P. Woodward) and Norfolk 

 (Miss Bell) ; but have frequently received S. annuus under 

 the name of S. perennis. . ?1^ A^ imj k^u ^liW*-^ h f.
