Quercus × bebbiana (or Quercus bebbiana), known as Bebb's oak, is a naturally occurring hybrid of white oak (Quercus alba) and burr oak (Quercus macrocarpa). It occurs where their ranges overlap in the eastern United States and eastern Canada.[1] It was named for Michael Schuck Bebb (1833–1895), an Illinois botanist who specialized in willows (Salix). Its parents are both placed in Quercus sect. Quercus.
A tree reaching 15m, and available from specialty nurseries, its acorns are sweet enough to be palatable to humans.[2]
