^fazama was the aboriginal designation of the Rocky Monnt- 

 ain goat, and was proposed also by Rafinesque as a generic name 

 for the same animal. The name is now well known tlirough the 

 organization of mountain-climbers called the Mazamas, who, on 

 August 21, 1896, with appropriate ceremonies, bestowed the name 

 ]Mount Mazama upon the mountain within whose walls Crater 

 Lake is enclosed. To this mountain and to the members of the 

 organization itself this plant is now dedicated.
