Swamp Tickseed (Bidens comosa)Observer
bmiller001Description
I am confused about the nomenclature with this one between B. comosa and B. tripartita. It certainly keys well to B. comosa in Michigan Flora. "Achenes retrorsely barbed on the margins their entire length (smooth and glabrous on the faces), achenes 3-awned and outer phyllaries are large and foliaceous".
