[HE LOGANBERRY A MYTH? 
strictly correct, nor is it correct 
to say that any real gametic 
splitting takes place. The plants 
are nearly all different one from 
another, but the differences are in 
minor characters, such as the 
length of the fruit, the amount of 
spines on the petiole and leaf and 
the color of the leaves. From an 
economic standpoint some are 
decidedly better than others; but 
there is no suggestion of either 
blackberry or raspberry. 
“Supposing that the Loganberry 
were a hybrid, but that it repro- 
duced itself asexually, after the 
manner of many plants, through 
the seeds, then one would not 
expect any variation at all, but 
all the seedlings should resemble 
the parent and one another. To 
test this, crosses were made with 
other species of the same genus." 
If the foreign pollen should act 
simply as a stimulus to make the 
plant reproduce itself asexually 
we should expect that there would 
result Loganberries, exactly like 
the parent; if proper fertilization 
should take place we should 
expect a great diversity of forms, 
corresponding to the segregation 
of the various characters in the 
supposed hybrid, Loganberry. 
“What actually happened was 
that the hybrids were remarkably 
constant, giving forms which were, 
looked upon broadly, intermed- 
iate between the Loganberry and 
the other parent chosen. Hybrids 
between Loganberry and raspberry
