Type locality: “Entangled thickets over the base of the hills 
which flank the village of Santa Barbara.” 
Distribution: Coast Ranges from Lake County southward to 
northern Lower California, also on the western slope of the Sierra 
Nevada. In southern California this is the most common shrub 
in the chaparral belt of the coastal mountains, but Jess common in 
the interior. On the desert slopes of the mountains it is seldom 
met with, being mostly replaced by the next species. As here 
understood the species has a great number of forms or variations, 
both in foliage and fruit. Upper Sonoran.

Quercus dumosa ae Jepson, Fl. Calif. 356. 1909. 
Type locality: “In the mountains of Lower California, where 
it is associated with the rare and characteristic Q. dunnit also 
within the borders of the State of California about Campo, in 
San Diego County.” 
Distribution: Inner South Coast Range from the Rancho Can- 
tera southward to Frazier Mountain according to Jepson. I have 
seen no specimens of this species except from the vicinity of Campo, 
where it is very common in the chaparral-covered mountains which 
form the divide between the coast slope and the Colorado Desert. 
Upper Sonoran. 
Specimens examined: Near Campo, dbrams 3552, 3553; Meikle,
