When identifying different oak tree leaves, five factors come into consideration. Look at the tips of the lobes, number of lobes on the leaves, color changes in fall, overall size of the leaves and the geographical location.
For instance, Brant’s Oak tree leaves can be easily distinguished from others because of their spiny shape. When they are immature, they tend to be lighter green. Caucasian Oak tree leaves, on the other hand, are semi-gloss green, and can grow up to 15 centimeters long and 5 centimeters wide. The leaves also have different number of lobes compared to Coast Live Oak and Common Oak tree leaves.
