Synonyms[2]
  • Quercus shumardii var. acerifolia E.J. Palmer

The epithet acerifolia means "maple-leaved." The venation of the leaves shows them to be technically pinnately 5-lobed but with the two middle lobes larger than the other three. This makes the leaves appear palmately lobed at first glance, similar to many maples leaves. Quercus acerifolia is a tree sometimes reaching a height of 15 meters (50 feet).[5][6]

The species is threatened by habitat loss.[7]

Groves of the tree are under cultivation in several locations, notably Stephens Lake Park Arboretum in Columbia, Missouri.[8]
