Discussion
Southern cottonwoods are nearly ubiquitous, although varying greatly in abundance, throughout the southeastern United States. They are among the fastest growing and largest trees in the region and are the basis for local poplar plantation forestry rather than hybrids used in other regions. Subspecies deltoides intergrades rather freely with subsp. monilifera up the Mississippi River drainage system, and traces of its morphological influence may be found as far north as Minnesota and Wisconsin (E. Marcet 1962).
