Lamium purpureum var. purpureum

From Flora of Indiana (1940) by Charles C. Deam

We have a single report for this species. I have specimens from four counties: from Jefferson County, frequent along the roadside along a creek northeast of Brooksburg; from St. Joseph County, in a cemetery along the St. Joseph River near South Bend; and from Tippecanoe County from nursery grounds in West Lafayette.
