MILLSPAUGH'S BLACKBERRY. 



I SHOULD like to correspond concerning the Southern Mountain Black- 

 berry, Rvbus Millspaughi Britton, with persons who are acquainted with 

 it or interested in the matter, and get specimens showing accurately the 

 leaves on the new canes as well as those on the old ones, the flowers, 

 forms of inflorescence and the fruit. Having read the literature on the 

 subject, Dr. L. H. Bailey's account in " Evolution of our Native Fruits" 

 and Dr. N. L. Britton's original description, Bull. Torr. Club, 18 : 366, 

 and examined the material in the Herbarium of the New York Botanical 

 Garden, and having recently received an interesting account of it from 

 Dr. C. F. Millspaugh, I think it should be treated as a species quite dis- 

 tinct from our northern Rjibus Canadeiisis L. with which I am well ac- 

 quainted, but I wish to be more certain as to it. 



I am informed that it is known as the ' ' Bear Blackberry ' ' and ' ' Oc- 

 tober Blackberry " and grows only on the higher Alleghanies from West 

 Virginia south. It appears to differ widely from our mountain black- 

 berry, being a much taller plant, really unarmed, with smaller flowers, 

 more upward pedicels and longer leaves. The fruit seems to be long 

 and slender, while ours is short-oblong or globose.
