(Quercus texana [Quercus nuttallii])
Family: Fagaceae

Description
Tree with swollen base and open crown of spreading to horizontal or slightly drooping branches. Height is 60–100 ft. (18–30 m). Diameter is 1–3 ft. (0.3–0.9 m). Leaves are 4–8 in. (10–20 cm) long, 2–5 in. (5–13 cm) wide. They are elliptical and deeply divided into seven or five narrow long-pointed lobes. They are dark green above and paler with tufts of hairs beneath, turning brown in the fall and shed in early winter. Bark is gray or brown and smooth, becoming black and furrowed into flat, scaly ridges. Acorns are 0.75–1.25 in. (2–3 cm) long, they are oblong and the tip is enclosed by a deep, thick cup.

Habitat
Wet, poorly drained clay soils of flood plains; sometimes in pure stands. Non-native to New Mexico.

Discussion
This tree was not distinguished as its own species until 1927, when it was named for the British-American botanist and ornithologist Thomas Nuttall. The foliage resembles pin oak, but the pin oak has smaller rounded acorns with a shallow cup.
