==Description==

Quercus glaucoides is primarily a canopy tree in its native habitat. It is an evergreen tree up to {{Convert|10|m|abbr=off}} tall with a trunk diameter of over {{Convert|40|cm|abbr=off}}. The leaves are thick and leathery, up to {{Convert|15|cm|abbr=on|sigfig=1}} long, with a few shallow rounded lobes.

Its scientific name is often misapplied to the NE Mexican and central Texas native Lacey oak (Quercus laceyi), which has caused great confusion about the true identity of this species and the correct scientific name for the Lacey oak. Although somewhat related, they do not share the same native range, with Q. glaucoides being endemic to Mexico, while Q. laceyi is native to both northeast Mexico and central Texas, and Q. glaucoides is evergreen, while Q. laceyi is deciduous.
