Branchlet of Quercus wislizeni, Cantor Center parking lot. Note unlike coast live oak, leaf undersides lack tufts of hair at the vein axils. Sairus Patel, 19 Sep 2018

The leaves are similar to those of coast live oak, but are flat, not concave, and do not have coast live oak’s characteristic tufts of hairs at the vein axils on the undersides. Otherwise, the leaf shape is quite variable. Hybrids of the two species are not uncommon.

See a small specimen of Q. wislizeni at the northwest corner of Museum Way and Palm Drive, fronting the parking lot of the Cantor Center (location, Sep 2018).

Variety frutescens (dwarf interior live oak) is found at Jasper Ridge Biological Preserve.
