338 ADDITIONAL SPECIES, ETC. 



many counties of England and a large part of tlie lowlands 

 of Scotland theii* apparent absence is merely the result of 

 their not being understood by those who have given to us 

 the several county lists. In the extreme north of Scot- 

 land and in the northern Isles it is probable that very few 

 species exist. In a list drawn up by Dr. Balfour and the 

 present writer, of the plants of N. Uist, Harris and 

 Lewis, a part of the N. Isles, R. corylifolius, R. fruticosus 

 and R. saxatilis are mentioned. It is now quite impossi- 

 ble to state what may be the true name of the fii'st of 

 these plants, but it is believed that the R. fruticosus is 

 R. discolor, and the R. saxatilis correct. No accurate ob- 

 servations appear to have been made upon the elevation 

 to which the fniticose Kubi attain, but it is highly proba- 

 ble that the range from the coast level in the Peninsula 

 to the height of 250 — 300 yards in the Highlands is 

 generally accurate, and as far as observation has extended 

 there seems to be no material difference between the so- 

 called species in this respect. 



The catalogTie of the counties in which the different 

 Rubi have been found, is chiefly derived from specimens 

 preserved in the writer's own herbarium ; but he has been 

 favoured with lists of the localities recorded in the col- 

 lections of the Eev. A. Bloxam, the Kev. W. A. Leighton 

 and F. J. A. Hort, Esq., on the authority of which many 

 counties have been added to the list ; the individual au- 

 thority for them being given within a bracket, as (B.), (L.) 

 or (H.) respectively. Those localities are similarly distin- 

 guished which the writer believes that he has himself 

 noticed, but from which no specimens exist in his col- 

 lection ; a few also are added from other authorities 

 which will be recognized by the marks appended to 

 them."
