DescriptionThe northernmost range of coast live oak (Quercus agrifolia) is reported from the Ukiah Valley (Mendocino County, California). Here, field observations suggest that hybridization with interior live oak (Q. wislizeni) is important. Elsewhere in northern California, morphology of coast live oak can be highly variable (particularly foliar form) and this has commonly been attributed to "noise" from a polymorphic species belonging to a genus renowned for its variability. This variability can be worrisome to scientists working on sudden oak death, since it may result in confounding species in ecological and pathogenicity studies.
