springy places. 
Quercus lobata Née. Fort Tejon, a few miles over the Los 
Angeles boundary, in Kern County, is situated in a grove of 
magnificent oaks of this species, some of them 7 and 8 feet in 
diameter. Within our limits it has been reported from La 
Liebre Rancho in Antelope .Valley.* A single tree has been 
observed by Dr. Hasse at Santa Monica. It may be expected in 
the intervening mountains. 
Quercus Douglasii H & A. This species barely reaches Los 
Angeles County on the desert side of the Liebre Mountains 
(Covzlle).
