Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 1 Sep 2004 e-mail from Jeff Greenhouse see Comment 1
Editorial Comments 1 Correspondence 1 indicates that Ralph E. Brooks and Steven C. Clemants, in Flora North America 22:217 (2000), treat Juncus mexicanus as Juncus arcticus Willd. var. mexicanus (Willd. ex Roem. & Schult.) Balslev (Brittonia 35:308. 1983).
Correspondence 2 9 Nov 2006 e-mail from Jeff Greenhouse see Comment 2
Editorial Comments 2 Correspondence 2 indicates that Juncus mexicanus was published in Systema vegetabilium, ed. 16, 7:178 (1829), and that the authors of vol. 7 are J.A. Schultes & J.H. Schultes (Schult. & Schult f. in Authors of Plant Names). [Therefore, author citation not incorrect as cited in this Index.]
Correspondence 3 30 Apr 2008 e-mail from Jeff Greenhouse see Comment 3
Editorial Comments 3 Correspondence 3 indicates: that, after looking further into the publication of Juncus mexicanus in Systema Vegetabilium 7(1):178 (1829), Greenhouse believes there is need to correct the conclusions in his Nov. 2006 e-mail about the citations for Juncus mexicanus and Juncus arcticus var. mexicanus; and that, although the authors of the work were Schult. & Schult. f., they ascribed the name to "Willd." (= Authors of Plant Names) and credited the Latin description to "Reliqu. Willd. MS.", in reference to unpublished manuscript material of Willdenow's left after his death (in 1812) and made available to the authors of Systema Vegetabilium. [Therefore, author citation corrected to Juncus mexicanus Willd., from Juncus mexicanus Willd. ex Schult. & Schult. f. previously in this Index, 30 Apr 2008.]
