Dipsacus fullonum B. S. Walters

The oldest Michigan collections seen are dated 1844 (presumably Macomb or Oakland Co.) and 1861 (“rare” in Washtenaw Co.). Apparently not spread much in the state until the second decade of the 20th century, and still very local in northern Michigan, while it is now common southward along roadsides and railroads, in fields and open disturbed ground, along trails and floodplain meadows.
