Southern Red Oak (Spanish Oak)
A large tree with a long, straight trunk, open, rounded crown and spreading branches.
Leaves alternate, simple, 7–9 inches long, with a rounded base; variable in shape; with 3–5 bristle-tipped lobes, first pair of lobes usually the largest and longest, often sickle-shaped, notch of the lobes wide and nearly to the midvein. Upper surface dark green, shiny; lower surface paler with light brown to grayish-white matted hairs. Leaves often droop; turn reddish-brown in fall. The 3-lobed leaves are distinctive.
Bark grayish-black, broken into deep grooves, becoming ridged and rough-plated near the base, not scaly. Inner bark only slightly yellow.
Twigs stout, reddish-brown, hairy at first, smooth later.
Flowers April–May, in catkins.
Fruits September–October, acorns single or in pairs, brown, faintly striped, round, ½ inch long; cup covering about 1/3 of the nut, thin, scales flattened, with a reddish-brown dark border, hairy. Ripening in autumn of the second year.
