Annotation: When described this was considered as the cross Q. alba L. × Q. muehlenbergii Engelm. However, progeny grown from acorns of the tree from which the type originated led Bartlett [1951] to conclude that the parents were in fact Q. macrocarpa Michx. and Q. muehlenbergii. If this conclusion is accepted, the name Q. ×deamii applies to Q. macrocarpa × Q. muehlenbergii, and not to Q. alba × Q. muehlenbergii. From Shenchen Code Art H.10.2. Note 2, ex. 6. See also Quercus × deamii Trel., Proc. Amer. Philos. Soc. 56: 49. 1917, without description.
Nomenclature Reason: Validly published by reference to the desciption and plate of Quercus alba L. × Quercus muehlenbergii Engelm. in Deam, Rept. Indiana Bd. Forestry, vol. 11, p. 127, pi. 44. 1912.
