Discussion
Plants in the Dakotas and south-central and eastern Canada are intermediate between subsp. nuttallii and subsp. rydbergii and were placed by R. W. Long (1966) in subsp. canadensis; C. B. Heiser et al. (1969) returned this to subsp. nuttallii with the comment that it was hardly equivalent to other subspecies that they included in their treatment. The name H. ×luxurians may refer to hybrids between subsp. nuttallii and H. giganteus (Heiser et al.).
