&c. From these materials, it is obviously impossible to 

 cany out my own mode of illustrating the distribution of 

 species, with the species of Rubi which have been gra- 

 dually carved out of the Linnean " fruticosus " and its 

 allied forms. If any botanist can and will do this, I shall 

 be happy enough to incorporate his achievement in a sub- 

 sequent volume of the present work. 



346. RuBUS Id^us, Linn. ^ /^^/-/».4'//' 



Area, general. 



South limit in Devon, Isle of Wight, Kent, ^^f^^^ ■ 



North limit in Orkney and Sutherland. 



Estimate of provinces 18. Estimate of counties 75. 



Latitude 50 — 60. British type of distribution. 



A. A. regions. Inferagrarian — Inferarctic zones. 



Descends nearly to the coast level, in the Peninsula. 



Ascends to 650 yards, in the East Highlands. 



Range of mean annual temperature 50 — 40. 



Native. Sylvestral, &c. Probably often dispersed by 

 birds from the gardens into the hedges and copses; but 

 apparently an indigenous production throughout Britain. 

 Neither this one nor any other species is included among 

 the plants of Shetland, by Edmondston, with the excep- 

 tion of R. saxatilis. Balfour and Babington did not meet 

 with it in the Hebrides ; but Dr. Neill observed it in 

 Orkney.
