General Discussion

Quercus x filialis Little J. Washington Acad. Sci. 33: 10. 1943.

This hybrid oak results from the crossing of willow and black oaks and is one of the more frequently occuring of the hybrid oaks in the New York metropolitan area. Intermediate in characters between the two parents, the leaves are tomentose abaxially and often appear linear to narrowly elliptic (blades usually wider than phellos) with 2 or more small teeth.
