Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 14 Feb 2003 e-mail from Jeff Greenhouse see Comment 1
Editorial Comments 1 Correspondence 1 indicates that Guy Nesom (The Jepson Manual [Ed. 1] author for Erigeron and Trimorpha), in a 1/31/03 e-mail to M. Wetherwax, states "molecular evidence unequivocal in indicating that Trimorpha arose from within a clade of more typical Erigeron. I'm treating it all within Erigeron for Flora North America", so that Trimorpha acris var. debilis is now to be treated as Erigeron acris L. var. debilis A. Gray.
Correspondence 2 21 Feb 2005 e-mail from Guy Nesom see Comment 2
