Bohemia Ecological Preserve

The Oregon Oak closely resembles its close relative, the Valley Oak. The leaves are deeply scooped, have rounded lobes and the bark is grayish-white checkers. The acorns are quite different. Oregon Oak acorns are round and fat, and Valley Oak acorns are slender. New leaves on the Oregon Oak have distinctive felted pink hairs. (The Valley Oak doesn't have these, but the Black Oak does.) There are no Valley Oaks at Bohemia - although there are 5 species of Quercus plus tanoak.
