Alternate Note:
The present treatment is provisional. It would be possible to recognize most, but not all our species as ~Deyeuxia~. However, until we have better evidence of the relationships in the complex, it seems best to retain all the taxa in ~Calamagrostis~. (rjs 2003). Newer molecular data indicates most of the New World taxa do not belong to ~Calamagrostis~ or ~Deyeuxia~, but to the ~Trisetum~ lineage s.l.
