432 THE EVOLUTION OP OUR NATIVE FRUITS 



Fig. 118. Truss of Fragaria Chiloensis. 



ing forms of this type are known as Fragaria Callfor- 

 nica and F. ylauca. Figs. 117 and 118 show some of 

 its characteristics, the thick, blunt-toothed leaflets, 

 low fruit -clusters with sprawling -rayed trusses, and 

 conical -pitted berries. It is possible that useful 

 varieties may be obtained from this North American 

 Chiloensis group, although the garden progeny of its 

 South American branch is already so good that there is 

 little reason for returning to the wild for a new start.
