24. ROSACE.E. 359 



Descends to the coast level, in the Peninsula. 



Ascends to 100 or 200 yards, in England. 



Range of mean annual temperature 51 — 47. 



Native. Septal, &c. The estimate of 60 counties may 

 possibly be too high for this species ; but I can specify 

 very few counties southward of the Forth and Clyde, from 

 which it is likely to be wholly absent. Peebles, Selkirk, 

 and possibly some others, may be without it. As may be 

 seen, I find no authority for its occurrence in the Lake 

 province. 



'u -A^-^/ .^- ^'^X-RosA ciNNAMOMEA, Linn. 



Area (10 * [12] 13). 



Alien. Said to have been found in the wood at Aketon, 

 near Pontefract, and at Birkhill, Galston, Ayrshire. Re- 

 cently, another locality has been given, on which Mr. 

 Borrer remarks, " The rose in Howrey Field, Keswick, 

 which has been mistaken for R. cinnamomea, is the Ame- 

 rican R. lucida. There are two plants of it in the hedge, 

 near the junction of the river Greta with the Derwent, and 

 they are spreading by their creeping roots." (Phytologist, 

 ii. 427). 



Rosa Dicksoni, Lindl. 



Hiberaian ? Reported to have been found wild in Ire- 

 land, which is rendered very doubtful by the remarks of 

 Mr. Mackay, in the Flora Hibernica.
