California black oak is a deciduous, hardwood tree with a broad rounded crown. It is the largest mountain oak in the West. The trunk bark is dark and covered with small plates. The bright green leaves are distinctly six-lobed ending in one to four bristle-tipped teeth. The acorns mature in the second year. The nut is deeply set in the cup and the cup is covered with thin, flat and imbricate scales. Source: USDA Plants Database
