| Miscellaneous | -- A. Camus : n° 176; -- Sub-genus Quercus, Section Quercus, Series Dumosae; -- Introgression with Q.dumosa, the "coastal scrub oak", or "Nuttall's scrub oak"; -- Today's taxonomists actually distinguish 2 different species : Q.dumosa in coastal ranges, and Q.berberidifolia going inland; moreover, plants native to Santa Catalina Island and other neighbouring islands, first considered as varieties of Q.dumosa, later identified to Q.berberidifolia, are currently named Q.pacifica. -- Different from Q.dumosa and from Q.durata var. gabrielensis (both have abundant hairs on the leaves undersides), from Q.cornelius-mulleri (still more pubescent beneath), from Q.john-tuckeri (glaucous leaves and larger acorns), and from Q.turbinella (glaucous leaves and stalked acorns); -- Hybridizes with many other Californian white oaks : see Q.x acutidens |
