Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 11 Aug 2009 e-mail from Jeff Greenhouse see Comment 1
Editorial Comments 1 Correspondence 1 indicates that Leymus X multiflorus was published by Mary E. Barkworth & Riley J. Atkins (Barkworth & R.J. Atkins in Authors of Plant Names) in American Journal of Botany 71:619 (May--June 1984), and that the publication with the same Gould basionym by Á. Löve in Feddes Repertorium 95(7-8):482 is dated October 1984, making the latter an isonym. [Therefore, author citation corrected to Leymus X multiflorus (Gould) Barkworth & R. J. Atkins, from Leymus X multiflorus (Gould) Barkworth & D. R. Dewey previously in this Index, 20 Aug 2009.]
