THE FLORA OF MOUNT RAINIER 



Vaccinium deliciosum Piper. 



This is the common bilberry of the alpine meadows of the Cas- 

 cade and Olympic Mountains in Washington, where it is abundant 

 at 4,500 to 5,500 feet altitude. In habit and fruit it resembles V. 

 caespitosum, but in floral characters V. ovalifolium, to which Dr. 

 Gray rather hesitatingly referred it. From this last it may readily 

 be distinguished by its serrulate leaves and low habit, its relatively 

 longer filaments, which in V. ovalifolium are only one half as long 

 as the anthers, and its small-seeded fruit of very different flavor. 

 Very young leaves have the serrulations tipped with small glandular 

 appendages.
