Oak leaves with rounded lobes - no bristles (awns)
Below: Bur Oak, Quercus macrocarpa Michx.: Ovate, broadest at the heart, (Fiddle-shaped) with many rounded lobes and a broad rounded tip that may resemble a crown every bit the tip lobes appear more every bit large teeth instead of lobes. There is considerable multifariousness on how deep the lobes cut to the primal rib. On some the indentations are slight, on others the two middle lobes are divided virtually to the central rib. Color is night green and slightly shiny on summit and gray-dark-green with fine hair under. The leafage stalk is short. Bases are rounded to pointed. Fall color is a rusty brown.
Below: Swamp White Oak, Quercus bicolor Willd.: Ovate with a triangular or narrow wedge shape base of operations and with a rounded point at the tip. The edges are non deeply cutting but with broad big teeth, either on the entire foliage or just the top half. At that place can be many variations. The upper foliage is a nighttime shiny greenish and the underside whitish with dense fine pilus. Fall color is yellowish to rusty chocolate-brown - not considered striking.
Beneath: White Oak, Quercus alba Fifty.: Ellipsoidal to ovate in shape, with a base that is a narrow wedge shape to triangular with the point forming the curt stalk. There volition be 7 to x (5 to 9 usually) ascending lobes looking like fingers, and a rounded apex at the height terminate of the leaf. The lateral lobes indent to the mid-vein by i/three to 7/8ths of the distance and these lobes besides have a somewhat rounded tip. The upper surface is a vivid gray-greenish and underside is more than whitish with erect hairs that disappear every bit the leafage matures. The secondary leafage veins are arched. Fall color can be yellow to yellowish-red to mulberry. Leaves from the juvenile part of the tree tin can resemble those of Swamp White Oak and Bur Oak.
Below: Chinkapin Oak, Quercus muehlenbergii Engelm.: Leaves occur merely on the current years twigs and are obovate to oblong in shape, upwards to 7 inches long and one-half equally broad, widest just above the middle, with a dark light-green leathery upper surface and a much paler underside. Leaf margins undulate with either teeth or shallow lobes, the teeth or lobes are rounded or more acutely upward pointed. Sinuses are defective. Leaf bases are truncate to cuneate (wedge-shaped). Secondary leaf veins usually number 10 to 14. The underside of the leaf lacks tufts of directly hairs institute in some other oaks but can have appressed stellate hairs.
Oak leaves with pointed lobes - with beard (awns). Oaks of this group tend to hybridize with each other.
Beneath: Black Oak, Quercus velutina Lam.: Elliptical, long stalked, usually with 5 to 9 (5 usually) lobes that are either shallow or deep and narrow with the sinus most the midvein rounded. Lobes cease with a few bristle-tipped teeth (awn. The leaf base of operations tin be obtuse to truncate in shape and is usually a bit unequal from side to side. The upper surface is shiny night green and the underside a stake dark-green with some brown hairs along the main veins. The secondary veins appear raised on both surfaces. Fall color is brown to dull red.
Below: Northern Cerise Oak, Quercus rubra Fifty.: Elliptical in shape, on a slender stalk, divided into seven to eleven shallow, wavy lobes fissure 1/three to 1/2 of the distance to the mid-vein. The lobes have bristly tips (awns) and are rounded in the sinus near the mid-vein. The upper surface is a duller green, the underside a tedious lighter green with tufts of hair along the mid-vein. Autumn color is ruby-brownish. A deeply lobed instance (like the 1st photo) will resemble Northern Pivot Oak shown below, just in viewing several examples note that the section along the mid-vein will generally have more than foliage. Nor are they equally shiny as Black Oak shown above.
Beneath: Northern Pin Oak, Quercus ellipsoidalis East. J. Loma: Elliptical, broadest across the lobes above the middle, and can be divided over half manner to the mid-vein with 5 to seven deep lobes (sometimes 9). Each lobe ends in several bristle-tipped teeth (awns). Between the lobes (the sinuses) the area is generally round. At that place is a short leaf stalk, a shiny green upper surface and lighter under with tufts of hair forth the mid-vein. The branching secondary veins appear raised from the surface. Fall colour is brown to a deep red.
Below: Pin Oak, Quercus palustris Münchh.: Of the nine oaks listed here, this one is fairly consistent in looks except for the base which tin can be truncate (1st photo) or birdbrained (second photo), otherwise, the leaf is elliptic to oblong in outline with 5 to seven deep lobes, cutting nearly to the mid-vein (much deeper than the Northern Pin Oak shown above). The sinuses of the lobes are irregular to rounded with the larger lobes forming a "U" shape. The lobes are tipped with pointed bristles (awns). The upper leaf surface is bright shiny green, the lower surface paler. Both surfaces are complimentary of hair except for tufts of brownish pilus on the underside at the veins. If the base is truncate in shape the base pair of lobes is oft recurved. Fall color is cherry to cherry brown.
Below: Scarlet Oak, Quercus coccinea Münchh.: Elliptical to oval in outline, securely divided, nearly to the mid-vein or at least half manner, with seven to 9 lobes, each lobe ending in bristle tipped teeth (awns). The sinuses betwixt the lobes are wide and round forming more than a one-half circle. Stalks are long and slender. Secondary veins of the leaf appear raised on both surfaces. The upper surface is a shiny light-green, the underside stake dark-green with tufts of pilus forth the mid-veins. The leaf tip is pointed, the base is blunt (truncate) to slightly pointed (obtuse). Fall color is scarlet.
