Cherrybark Oak Leaf, Scientific Name: Quercus pagoda Here again, this leaf has lobes that are blunt and curved. Its 15-cm long and 5-cm broad leaves are semi-glossy green. Caucasian Oak leaf, Scientific Name: Quercus macrantheraĬaucasian oak is a rarely seen oak tree, it is sometimes called Persian Oak, too. ![]() Another easy way to identify this leaf type is by noticing that this leaf is geometrically flat. They are typically glossy dark green on the upper side. The lobes of the leaves are typically sharp-tipped, and have bristles at the lobe tip. This tree is also commonly termed as Golden Cup Oak. Canyon Live Oak Leaf, Scientific Name: Quercus chrysolepis The leaf is green above and pale, fuzzy underneath. The lobes at the leaf’s tip look like a crown. ![]() The two sinuses in the center divide the bur oak leaf into almost half. The bur oak leaves are roughly obovate in shape, and have many lobes. So if you know there’s an oak tree in your neighborhood, you can identify its name from the following tips. It’s not possible to list the characteristics of all types of oak tree leaves, but now that you generally know how the oak tree leaf looks, the following descriptions may make leaf identification a less arduous task. The leaves change color in fall taking on a bright gold or scarlet or russet hue. The leaves are arranged in a spiral manner, and may also be seen as bunches attached by short leaf stalk or petiole in some oak tree species. ![]() Some leaves have tufts of hair near the veins on the underside. The leaves are green, often leathery on top, and pale underneath. Some leaves are serrated or toothed with smooth margin. The leaves may have a lobed margin, or a smooth margin in the entire leaf. The number of lobes may be from 5 up to 20 in a leaf. The characteristic features in an oak leaf are its lobes and sinuses (space between the lobes). Oak tree leaves may be deeply pinnatifid-like seen in Canada. The shape of the leaf may be ovate, obovate and sometimes, elliptic. Because they don't sprout till the following spring, red oak acorns are an important fall and winter food source that will carry deer, turkey, ducks, squirrels, and songbirds through the entire season on years with a good mast crop.The oak tree leaf is broad, thin and flat and is called a broadleaf. Red oaks may start dropping acorns before white oaks, and may continue to drop after white oaks are gone (this depends on species and individual trees). White oaks either sprout or are eaten quickly by wildlife, so they are often a short-lived food source that should be capitalized on quickly during deer season. Some species of white oak produce acorns that are mild enough for humans to eat raw. Because of this, white oak acorns are less bitter, sometimes even sweet, and are usually the preferred acorn for deer and other wild game. White oak acorns sprout shortly after they fall, so they do not require the high tannin levels to resist rotting. The tannin preserves the acorn over the winter so it can germinate and sprout in the spring. ![]() Red oaks produce acorns with higher tannin levels. However, preference may vary from one tree to the next, and often depends on what kind of acorns are available in your area. Deer generally prefer acorns with less tannin. Most acorns contain tannic acid (tannin), a very bitter substance used in tanning leather. You may find both mature and immature acorns on the same tree. Red oak acorns take two, occasionally three years to reach maturity. White oaks produce acorns within one growing season - acorns ripen the same year they were pollinated. Oak trees bloom in the spring, pollinating by wind through male and female flowers (catkins). ![]()
