Akala, a Giant Hawaiian Raspberry. (Rubus macraei A. Gray; 

 S. P. I. No. 53847.) 



Recent investigations have brought to light several species of Rubus which promise to prove of 

 value to plant breeders. One of the most striking of these is the Akala of Hawaii, whose fruits 

 sometimes attain 2 inches in diameter. It is not sufficiently hardy to be cultivated in the Tem- 

 perate Zone, but through crossing with northern raspberries may give rise to new forms of 

 great value for the southern United States. (Photographed by J. F. Rock, Honolulu, Hawaii,
