--><p><i>Boltonia decurrens</i> is known only from the flood plains of the Illinois and Mississippi rivers. Present-day populations are isolated and restricted to disturbed alluvial habitats, old fields, roadsides, and disturbed wet lake shores that replaced its natural habitats of flooded lake shores and marshes. It is in the Center for Plant Conservation’s National Collection of Endangered Plants.</p>
