Taxonomy Comments: "Q. triloba Michaux", the form with the leaves only shallowly trilobed at the apex, can cause confusion. Though even medium-sized trees sometimes have leaves only of this form (rather than the typical form, deeply 5-7-lobed, the terminal lobe long-attenuate and falcate), it has no taxonomic merit.
