360 THE EVOLUTION OF OUR NATIVE FRUITS 



Red Antwerp cross. The fact that hardly a trace of the 

 raspberry remains in vine, leaf, or general appearance 

 supports this view." 



At this writing, the Logan -berry has not been suf- 

 ficiently tested in the east to enable one to pass upon 

 its merits as a competitor of the blackberry and dew- 

 berry. (See Bulletin 45, Rhode Island Experiment 

 Station, for an account of its behavior in the east.) 

 Although I have not had opportunity to study this 

 berry in the field, I am unable to detect evidences of 

 hybridity in herbarium specimens of it; and it does 

 not appear to present characters which could not 

 readily be derived directly from Rubus vitifolius. 



Another western blackberry which has been much 

 talked about, and which is said to be very promising for 

 the Pacific coast, is the Oregon Everbearing blackberry. 

 It has also been called the Evergreen and Climbing 

 blackberry. This is Rubus laciniatus, a plant long ago 

 described by Willdenow, and the nativity of which is 

 unknown. It is now generally agreed that it is a 

 cut -leaved form of the common European bramble or 

 blackberry, Rubus fruticosus. It has long been in cul- 

 tivation as an ornamental plant, and it has distinct 

 merits in this capacity; but in the eastern states it has 

 never attracted attention for its fruit. 



A blackberry which has been singularly overlooked 

 by botanists is one which was described by Bigelow in 

 his "Florula Bostoniensus" as long ago as 1824, as 

 Rubus setosus (Figs. 80, 81). This was thought by 

 Torrey and Gray, in the "Flora of North America," 

 to be a form of Rubus hispidus. A most careful 

 study of it has been made by Professor Peck, state 

 botanist of New York, who, not recognizing it as
