Quercus welshii has an elaborate root system that helps stabilize soils in sandy desert scrub communities.[3]:143

Elliptical or lance-shaped leaves with 6-10 lobes along the margins, with pointed tips, sometimes with lobes and teeth.[3]:143

Leaves are up to 1⁄2 to 2 inches (1.3 to 5.1 cm) long with dense hairs on both sides, becoming smooth with age.[3]:143

Quercus welshii is well anchored in sandy soils by complex root systems.[3]:143

Inflorescence and fruit

Quercus welshii blooms from March to June.[3]:143

Male and female flowers are in separate hanging clusters.[3]:143

Acorns are 1⁄2 to 3⁄4 inch (13 to 19 mm) long.[3]:143
