188 MODERN STRAWBERRY GROWING 
berries are lineal descendants of the botani- 
cally known Fragaria ananassa and Fragaria 
grandiflora or common old Pine class. 
The question now arises, ‘‘What is a Pine 
strawberry?” Bailey in studies on this sub- 
ject, in order to determine for himself, sent 
to Oregon for wild plants of Fragaria Chilen- 
sis. These were quite easily distinguished 
from ordinary garden strawberries, owing 
to the fact that they were short, stocky, 
thick-leaved, hairy evergreen plants. After 
two years of close observation he was able 
to find a remarkable difference between a 
pressed plant of the Oregon species and 
plants of the same species that had been 
under cultivation during this period. In 
fact, the characteristics of the wild plants 
under culture had changed so much that it 
was quite difficult to recognize them from 
ordinary garden sorts. This change was 
brought about undoubtedly by the variation 
induced through the changed environment 
of the plant. It is a well-known fact that 
such is the case in other plants. If artificial 
selection is then given, plants may be changed 
to a still greater degree.
