Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 25 May 2004 e-mail from Jeff Greenhouse see Comment 1
Editorial Comments 1 Correspondence 1 indicates that Peter F. Zika published Juncus effusus subsp. pacificus (Fernald & Wiegand) Lint ex Zika (Brittonia 55:152. 2003), based on Juncus effusus var. pacificus, and that he ascribed the combination at the rank of subspecies to Lint.
Correspondence 2 19 Dec 2006 e-mail from Jeff Greenhouse, including excerpt from 19 Dec 2006 e-mail from Peter F. Zika (Author of Juncus for The Jepson Manual [Ed. 2]) see Comment 2
Editorial Comments 2 Correspondence 2 indicates that, according to Peter F. Zika (Author of Juncus for The Jepson Manual [Ed. 2]) and International Plant Names Index, the combination Juncus effusus L. subsp. pacificus was first published by Piper & Beattie (Fl. N.W. Coast 88. 1915), based on Juncus effusus var. pacificus Fernald & Wiegand (Rhodora 12:89. 1910), so that the subspecific combination by Zika (2003) is superfluous. [Therefore, author citation corrected to Juncus effusus L. subsp. pacificus (Fernald & Wiegand) Piper & Beattie, from Juncus effusus L. subsp. pacificus (Fernald & Wiegand) Lint ex Zika previously in this Index, 4 Jan 2007.]
