Great Lakes Dewberry (Rubus perspicuus L.H. Bailey)

POWO has merged this species into windham county blackberry (Rubus ×flavinanus), but their range map does not show that species as occurring in Michigan and Wisconsin where this species is reported, which does not make sense. We have not yet resolved this discrepancy and have kept these taxa separate until we do so.

This tentative map is based on our own research. It may have limited data on Canada and/or Mexico, and there is some subjectivity in our assignment of plants as introduced vs. expanded. Read more in this blog post.
