Discussion

Subspecies wislizeni is the common cottonwood of the Rio Grande and Colorado Plateau regions, where it forms relatively small, scattered groves. It is a fairly homogeneous and distinctive southwestern part of the species. It intergrades with subsp. monilifera on the eastern and northern margins of its range. Populus sargentii Dode var. texana Correll is based upon such intergrades.
