MILLSPAUGH'S BLACKBERRY 323 



Virginia, at an altitude of 3,500 feet. It appears to 

 be specifically distinct from the common bush black- 

 berry, and it has recently been described as a new 

 species by Dr. Britton under the name of Rubus 

 Millspaugliii (Bull. Torr. Bot. Club, xviii. 366, Dec. 

 1891). Dr. Britton knew no other specimens than 

 those of Millspaugh, except a single leaf of it in Lin- 

 naeus' herbarium, in London, collected by Kalm over 

 a century ago.* I am inclined to think, however, that 

 the species is generally distributed over the northeastern 

 states. I have recently had good specimens of it from 

 the highest mountains of the Smoky range, North 

 Carolina, above 6,000 feet, collected by Chas. A. Kofoid 

 and Mr. Beardslee. In Walter Deane's herbarium, at 

 Cambridge, Mass., there is a specimen of it from Ice 

 Gulch, Randolph, N. H. (White Mountains), collected 

 by J. R. Churchill in 1889, and Mr. Deane says that 

 there is another specimen in the Gray herbarium from 

 the Keweenaw peninsula, Lake Superior, collected by 

 J. W. Robbins many years ago. I have had canes of 

 a perfectly smooth blackberry sent me from northern 

 Michigan (near Grand Traverse), and I have no doubt 

 that they belong to this species, as the angular and 

 furrowed, perfectly smooth canes of Rubus Millspaughii 

 are easily distinguished from those of the common 

 blackberry. From all these records, it would appear 

 that the species occurs upon our northern borders, and 

 that it follows the mountains southwards ; and this 

 accounts for the finding of the specimen by Kalm, who 

 traveled in Canada. 



"Now, as the canes of Rubus Millpaughii are per- 



* Linnaeus described the plant us Jtubn* Canadenti*, and that name must 

 replace R. Millspaughii, as explained in the succeeding pages. I,. H. B. 1898.
