Morus rubra L. Mellichamp

Floodplains, river bottoms, and swamps.

A scarce small tree, the very large, usually unlobed leaves are suggestive of a large leaved Tilia. The leaves are sometimes rather scabrous above. In Ontario, the small, isolated populations of M. rubra are threatened by hybridization with the common M. alba (Burgess & Husband, 2006). Ambiguous specimens that may be hybrids have been noted in Michigan, but more study is needed.
