	Juglans californica, generally found in the southern half of the state, can be either a large shrub with 1-5 trunks, or a small single-trunked tree. The main trunk can fork close to the ground making it look like two trees that have grown together, then diverged. It has thick bark, deeply channeled or furrowed at maturity. It has large, [[pinnate]]ly compound leaves with 11-19 [[lanceolate]] leaflets with toothed margins and no hair in the vein angles<ref>Kershner, Mathews, Nelson, and Spellenberg, ''National Wildlife Federation field Guide to Trees of North America'', 2008, Chanticleer Press, Inc. p. 229</ref>. It has a small hard nut in a shallowly grooved thick shell that is difficult to remove.
