Quercus shumardii W. W. Brodovich

Swamps, often on clay soils, mostly on the Lake Erie and Lake St. Clair lakeplain. This is a large tree of swamps, with very large, deeply lobed leaves, and large acorns. It has been reported regularly (but erroneously) from Michigan in the past (see Michigan Flora under Q. rubra), but a few authentic collections of Q. shumardii are now known. Collections from uplands with large, shallow-cupped acorns resembling those of Q. rubra (cups at least 2 cm broad) but the leaves more deeply lobed may be hybrids of Q. rubra with Q. ellipsoidalis. These can be distinguished by their smaller, hairy buds.
