Discussion
Subspecies monilifera is the abundant cottonwood of the Great Plains and extends sparsely through the Rocky Mountains to the Columbia Plateau. It intergrades with subsp. deltoides in a band along the southeastern edge of the Great Plains to the Great Lakes region. These intermediates have longer pedicels and may have 3–5 elongate basilaminar glands. It intergrades also with subsp. wislizeni along the southwestern margin of the Great Plains, where there are plants with longer pedicels and preformed leaves with fewer teeth and without basilaminar glands.
