Quercus falcata (Southern red oak)
Wasowski, Sally and Andy
Southern red oak is a medium-sized, straight-trunked oak which, in time, develops long, spreading branches, giving the top an even, well-formed appearance. Its smooth gray bark becomes dark and furrowed, eventually becoming black. Thin, papery, lobed, bristle-tipped deciduous leaves turn reddish-brown in fall. Twigs pubescent reddish-brown twig with star shaped pith; reddish-brown terminal bud is ovoid and pubescent. Leaf petiole 3/4 - 2 3/8 inches (19 - 60 mm) in length, smooth to sparsely pubescent; leaves are elliptical to ovate, 4 - 11 3/4 inches (101 - 298 mm) long and 2 3/8 - 6 1/4 inches (60 - 159 mm) wide, u-shaped base, margin has 3 - 7 deeply divided lobes with 1 - 3 bristle-tipped teeth, apex longer than lateral lobes; upper surface a glossy green often with some pubescence along midrib, lower surface covered with gray or tawny pubescence, secondary veins raised on both surfaces.

Often called Spanish Oak, possibly because it commonly occurs in areas of the early Spanish colonies. It is unlike any oaks native to Spain. The lumber is marketed as Red Oak. Cherrybark Oak (Q. pagoda Raf.) is sometimes considered a variety of Q. falcata (Q. falcata var. pagodifolia Ell). The lobes of its leaves taper to points that remind some people of the graduated roofs of pagodas. The leaves have 5-11 broad shallow lobes and whitish hairs beneath, and the bark is smooth and cherry-like with short ridges.
