It is in the red oak section Quercus sect. Lobatae. It is often confused with and closely related to the Quercus laurifolia (swamp laurel oak) in which it differs in several key characteristics.

Description
Quercus hemisphaerica is a medium-sized evergreen to semi-evergreen tree which can grow as tall as 35 meters (115 feet) with a trunk diameter of 1.5 m (5 ft), although it is more commonly around 18–20 m (59–66 ft) tall. The leaves are entire, without teeth except one apical awn (rarely with a few teeth near the apex), mostly elliptical or narrowly ovate, and 3–12 centimeters (1+1⁄8–4+3⁄4 inches) long by 1–4 cm (3⁄8–1+5⁄8 in) wide. The petiole is very short, ranging from 1–5 millimeters (1⁄16–3⁄16 in) long, and the leaf base is obtuse to rounded. The acorns are hemispheric in shape and 9 to 16.5 mm (3⁄8 to 5⁄8 in) by 9 to 16.5 mm (3⁄8 to 5⁄8 in). The acorns take 18 months to mature and are a fourth to a third covered by a saucer- to bowl-shaped cap.
