Type locality: “I have only seen branches collected at Monterey 
and Nootka, by the marine officer Don Robredo, and Don Manuel 
Esquerra, paymaster of the corvette Atrevida.” The above is 
copied from the translation of Nee’s paper in the Annals of Botany 
(2: 106. 1806). The station “Nootka” must be erroneous. 
Distribution: Mendocino County southward through the Coast 
Ranges to Mt. San Pedro Martir, Lower California. In southern 
California this oak is confined to the coast slope, even becoming 
very uncommon in the interior valleys. Its most eastern station 
is in the mountains between Campo and Jacumba Hot Spring, 
San Diego County. Upper Sonoran. 
Specimens examined: Sespe Hot Springs, Dudley 4781; Switzer’s 
Camp, San Gabriel Mountains, Grinnell, Oct. 8, 1908; near

Quercus morehus Kell. This oak is apparently a hybrid be- 
tween Q. Kelloggii and Q. Wislizeni. It is never found except in 
the vicinity of these species, and never in large numbers. ‘Two 
trees have been discovered recently in southern California: 
between Swartout Valley and Lone Pine Canyon, San Gabriel 
Mountains, Abrams &¥ McGregor 666; near Skinner’s Camp, Mill 
Creek, San Bernardino Mountains, dbrams &% McGregor 819.

Distribution: Southern Oregon southward through the Coast

in the lower part of the Transition Zone and extends into the 
Upper Sonoran along the canyons.
