Brewer's oak is a rounded to spreading, deciduous
shrub growing to about 15' in height with thin, scaly, grayish bark
becoming widely ridged. Its close relative, var. garryana
(called oregon oak), is a tree reaching some 60' in height, but that
taxon is not present in Southern California. The leaf blades are
1-1/2" to 3-1/2" long, oblong to obovate in outline, pinnatifid
into 5-7 entire-margined lobes (sometimes with 2 teeth), and with an
obtuse to rounded tip. The upper surfaces are a shiny, dark green,
while the lower are short-hairy and a dull light-green. The male
inflorescences are catkins about 1" to 2" long on the proximal
tips of twigs, and the female inflorescences are short-stalked and axillary
among the upper leaves. The fruit is an ovoid to sub-globose acorn,
3/4" to 1" long, with a shallow cup maturing the first autumn.
Brewer's oak may be found on dry slopes, 2500' to 5000', in chaparral
and yellow pine forest in the Tehachapi and Liebre Mts areas.
