IS THE HYBRID ORIGIN OF! 
HE Loganberry, one of the 
most popular members of 
the genus Rubus, came to 
light about 1881, in the 
srounds of Judge J. H. Logan of 
Santa Cruz, Cal. It was described 
by him as a natural hybrid which 
appeared spontaneously, and he 
believed that the parents were 
the Aughinbaugh (a variety of 
Rubus vitifolius, the wild blackberry 
of California) and a red raspberry, 
probably the variety Red Antwerp, 
since these two were growing near 
together in his yard. The fruit of 
the Loganberry is, in many 
respects, intermediate between the 
blackberry and red raspberry, and 
Judge Logan’s account of its 
origin was accepted as probable. 
It has since then been universally 
described as a chance natural 
hybrid. 
In later years, numerous arti- 
ficial hybrids between blackberries 
and red raspberries were secured, 
Primus and Phenomenal being the 
best known ones. These were in 
many respects similar to the Logan- 
berry, and supported a belief that 
the latter was a hybrid of similar 
nature. 
But evidence which is now 
accumulating indicates that this 
belief is wrong. The question 1s 
squarely put by W. O. Backhouse, 
Economic Botanist to the Argen- 
tine Government, who writes to 
this association from Buenos 
Aires under date of July 4, 1916,
