Sawtooth Oak2


The leaves of the sawtooth oak are unlobed with jagged teeth around the edges. The teeth have long bristles at their ends. These bristles make the leaf edges look like a saw blade which helps give the tree its name. The leaves are long, thin, and slightly spear-shaped. As with all oaks, the fruit of the sawtooth oak is an acorn. The acorns are easily recognizable by their shaggy cup. The curled scales on the top of the acorn look like hair. We recommend not sampling the fruits & nuts of the trees and plants here at Adventure Science Center.
