Found in very weedy habitat with Datura, Queen Anne's Lace, Feverfew and Common Sunflower. Plant about 3 ft tall, unbranched until the very top. Stem strongly squared, rough to the touch. Leaves stalkless, slightly clasping, opposite, somewhat toothed, about 4 time longer than wide. Thanks so much, -Corey
Yeah that looks like it. No wonder I couldn't find it, I don't think it is known form Wisconsin yet. Thanks a lot. -Corey
