Quercus texana (Nuttall oak)
Wasowski, Sally and Andy
Nuttall oak typically matures to about 75 feet in height and spreads about 60 feet, though some specimens can reach 140 feet with a spread of more than 100 feet. It is a deciduous oak known for its red to orange red late-fall foliage. Its bark is grayish-brown to black and furrowed with flat ridges. Similar to Pin Oak (Quercus palustris); but its acorns are more elongate. Acorns egg shaped and up to 3/4 inch long.

Not distinguished as a species until 1927, when it was named for Thomas Nuttall (1786-1859), British-American botanist and ornithologist. The foliage resembles Pin Oak (Quercus palustris); the ranges overlap in Arkansas, but Pin Oak has smaller rounded acorns with a shallow cup. Often confused with Buckley Oak (Quercus buckleyi) which was once illegitimately called Quercus texana.
