Native. Sylvestral, &c. Without intending to maintain 

 that all our fruticose Rubi, between caesius and Idaeus, are 

 referrible to a single species, I am still under the necessity 

 of treating their distribution in the aggregate. It is useless 

 to compile or collate localities published in books or com- 

 municated to me in writing ; because different botanists 

 have applied the same names so variously, that any such 

 course would result only in a compilation of errors and 

 suppositions. If I look to the specimens in my own her- 

 barium, I am almost as much at fault ; being unable to fit 

 the specific characters laid down by authors on the species 

 to the particular specimens in my herbarium. And if I 

 look to the labels of those which have been given to me 

 ready- labelled by other botanists, I find their names 

 crossed and applied in the most confusingly varied man- 

 ner. On turning to the latest, and probably much the best 

 account of the species, real and supposed, ' Babington's 

 Synopsis of the British Rubi,' I find the account of their 

 distribution confined to the mention of a few isolated lo- 

 calities, or the general expressions of " rare," " common,"
