A LIST OF 



BRITISH EOSES 



BY 



Major A. H. WOLLEY-DOD. 



As I shall be leaving England this autumn to reside abroad 

 at least for the greater portion of the next two years, I must 

 reluctantly drop the study of Roses, though I hope the cessation 

 will only be temporary. 



My regret at this step is the greater, since I have made very 

 little progress in my knowledge of the genus during the past two 

 years, partly on account of my own indisposition, but chiefly owing 

 to Prof. Dingier having been compelled through ill-health to lay 

 aside his work on the Roses of Europe, so that, with the exception 

 of a few of the Stylosa group, the whole of my collections of the 

 last two years has been returned by him unnamed. I had post- 

 poned further study of the genus in anticipation of his assistance ; 

 but as that has unfortunately not been forthcoming, I must present 

 the British list in a lame and uncertain fashion ; indeed I should 

 have made no advance in the genus but for the kind assistance of 

 M. Sudre, who has seen all my own specimens of the past two years. 



In this paper I propose to give a revised list of the British 

 Roses, including all the names I have received from Prof. Dingier 

 and M, Sudre, with a few brief remarks on them, indicating by 

 the use of square brackets those names which seem to me to be 

 undesirable for retention at present, owing to their introduction 

 having been based on insufficient material, or because the characters 

 of the specimen referred to them appear to me to be too much 

 opposed to tlieir descriptions. I have added a reference to the 

 author's description in the case of those species whicli will pro- 

 bably have to be retained, but for the sake of brevity I have not 

 given the descriptions themselves. I have also indicated the vice- 

 counties in which the specimens which I have myself seen have 

 been collected, and have included a certain number from the 

 herbaria of others, which have been sent to me for naming ; but 

 on none of these have I had an opportunity of ol)taining the 

 opinion of either of the two above-mentioned autliors. In cases 

 of more than ordinary doubt, a query follows the vice-corn ital
