possible hybrid? leaves seem especially flat, shallow-lobed.
Mystery oak
Somewhat speculative based on nearby observations of Q. lobata and Q. douglasii proximal to one another, as well as aberrant bark and leaf shape, combined with massive size and galls more strongly associated with Q. lobata.
Within 15' of preceding Quercus observation.
Already documented same tree (6/10/18) but corrected location:
Mystery plant of the day. Was staring in the hot sun at maybe too many Valley, Blue, and Coast Live Oaks today at Arastradero. Did a double-take since this guy’s leaves are noticeably bluer than Valley Oaks and not as deeply lobed, leathery, and with a fuzzier underside. Reminded me of the Jolon Oak at Stulsaft Park on the west service road-trail. Last photo shows a Spined-turban and a CA gall wasp gall.
Going to check the Jolon Oak for galls. First, more basic photos.
Oak fans! Whaddya think? Small oak outside the Henry Coe Visitor Center. Hinting at a couple of galls on it. More of those later. Saw thousands of Blue and Valley Oaks this weekend. Plus Coast Live and CA Black.
