The mountain mahogany is eommon on the higher summits of some 

 of the desert ranges, and was reeorded from the following localities: 



CALIFORNIA. 



Panamint Mountains. — A grove of large and handsome mountain 

 mahogany trees occupies the bottom of a canon above the abandoned 

 charcoal kilns at the north base of Telescope Peak, whence straggling 

 trees pass over the summit of the Panamint Eange north of the Peak 

 at an altitude of 2,560 meters (8,400 feet). Others were found on the 

 north slope as high as 3,660 meters (9,300 feet). 



High Sierra. — On the east (Owens Valley) slope of the High Sierra 

 the mountain mahogany is found in abundance, and of unusually large 

 size. West of Lone Pine it grows in a zone from 2,285 to 2,900 meters 

 (7,500 to 9,500 feet) altitude, and many of the individual trees attain a 

 diameter of a foot.
