Quercus douglasii. BLUE OAK. California
Native in the immediate vicinity of campus, the deciduous
blue oak grows along with coast live oak and valley oak. The leaves are noticeably
bluegreen and are lobed shallowly, if at all. Off Santa Teresa Street, there is
a parking lot in front of Roble Hall carved out of an original grove of blue oak.
A similar grove is up the hill where Lomita Court leaves Lomita Drive. A majestic
blue oak is to the right of the Dinkelspiel Auditorium entry stairs; two large
specimens at 247 and 267 Santa Teresa Lane guard the front of two faculty homes
opposite Governor’s Corner. More blue oaks are in the Tresidder Union parking
lot across from the Faculty Club, and they dot the native landscape between Campus
Drive West and Sand Hill Road.
FAGACEAE (Oak or beech family)
Sometimes the leaves of blue oak are lobed so as to resemble valley oak (Q. lobata), but in such cases the dome-shaped habit and modest height (around 40 feet) clearly diferentiates it from the more irregularly picturesque and often gigantic valley oak. It is named after David Douglas (see also Pseudotsuga douglasii).
