a The Jepson Manual [Ed. 1]
b Preston e-mail of 5 Jul 2000, "S[cirpus] cernuus (Roemer & Schultes) Vahl = Isolepis cernuus Roemer & Schultes; Smith, S. G., and G. Yatskievych. 1996. Notes on the genus Scirpus sensu lato in Missouri. Rhodora 98:168-179"
Initial Editorial Comments reportedly treated in Flora North America as Isolepis cernuus by Galen Smith, one of three The Jepson Manual [Ed. 1] contributors of Scirpus; see Source b; Isolepis treated as feminine, so epithet should be spelled "cernua" when combined with Isolepis
Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 21 Feb 2003 e-mail from Jeff Greenhouse see Comment 1
Editorial Comments 1 Correspondence 1 indicates that Scirpus cernuus was published by Martin Vahl (1749-1804; Vahl in Authors of Plant Names) in Enum. pl. 2:245 (1805), with no reference to a basionym by Roemer & Schultes or anyone else; that all The Jepson Manual [Ed. 1] drafts of the Scirpus accounts [including the published account] give Vahl as the citation, without parenthetical authors; and that the addition of "(Roem. & Schult.)" to the author citation was made in the Jepson Globe (see also http://ucjeps.berkeley.edu/all_corr2.html), without explanation. [Author citation corrected to Scirpus cernuus Vahl, as in The Jepson Manual [Ed. 1], from Scirpus cernuus (Roem. & Schult.) J. Vahl originally in this Index, 10 Mar 2003.]
Correspondence 2 Treatment and author notes submitted for The Jepson Manual [Ed. 2] by S. Galen Smith see Comment 2
