It is remarkable that this species should have been 

 hitherto placed in the vicinity of Rosa cinnamomea, which 

 it does not resemble in the least, and that it should at the 

 same time have been separated widely from RosA^/erar, 

 which it approaches so nearly that the two can scarcely be 

 discriminated by any describable permanent character, and 

 yet no two species can be more truly distinct. 



In kamdiatica the leaves are less shining, and the stem 

 less prickly than in ferox. In the latter the prickles imme- 

 diately under the stipulse and those of the branches are 

 equal in size, and of nearly the same form ; but in 'kamcha- 

 tica the stipulary prickles are large and falcate, those of the 

 branches setiform and minute. Ferox retains its leaves, and 

 their verdure till late in the autumn, those of kamchatica 

 fall off soon after the summer heat has commenced. 



The leaves of the specimen which Sir J. Smith described 

 in Rees's Cyclopedia are more obovate and retuse than those
