General Discussion

Quercus x heterophylla Michx. f. Hist. Atrb. Amer. Sept. 2: 87, pl. 16. 1812.

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