Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 5 Dec 2002 e-mail from Jeff Greenhouse see Comment 1
Editorial Comments 1 Correspondence 1 indicates that the correct author citation is Juglans hindsii (Jeps.) Jeps. ex R. E. Sm., abbreviated to Juglans hindsii (Jeps.) R. E. Sm. This is based on the fact that Ralph E. Smith, in publishing the species name, Juglans hindsii, in 1909 (Univ. Calif. Agric. Exp. Sta. Bull. No. 203, Report of the Plant Pathologist, p. 27), referred to Juglans hindsii Jeps. (thereby ascribing his species name to Jeps., yielding Jeps. ex R. E. Sm.), which evidently has never been published. The reference to this unpublished species name has been considered by Strother (pers. comm. to Greenhouse) sufficient for its time to serve as an indirect reference to Juglans californica S. Watson var. hindsii Jeps. (1908. Bull. S. Calif. Acad. Sci. 7: 24), which had been published.
Correspondence 2 25 Nov 2003 e-mail from Jim Dempsey, Northern Buttes District, Oroville Headquarters, California Department of Parks and Recreation see Comment 2
Editorial Comments 2 Correspondence 2 indicates that it is not true that the name Juglans hindsii Jepson has never been published [as was incorrectly assumed by the Editor from Correspondence 1], that it was, in fact, published by Jepson, in 1917 (Madroño 1:57). [Since it was published after Smith's name, it is to be rejected as an illegitimate name because it was nomenclaturally superfluous when published.]
Correspondence 3 26 Nov 2003 e-mail from Jim Dempsey, Northern Buttes District, Oroville Headquarters, California Department of Parks and Recreation see Comment 3
Editorial Comments 3 Correspondence 3 indicates several publications in which this taxon is treated as a species, including: Thomsen, H. H., 1963. Juglans hindsii, the Central California Black Walnut, Native or Introduced? Madrono, 17(1):1-32; McGranahan, G. H. & John Hansen, 1988. Inter- and Intraspecific Variation in California Black Walnuts. J. Amer. Soc. Hort Sci. 113(5):760-765; Fjellstrom, R. G. & D. E. Parfitt, 1994. Walnut (Juglans spp.) genetic diversity determined by restriction fragment length polymorphisms. Genome 37:690-670; and Stanford, A. M., R. Harden, & C. R. Parks, 2000. Phylogeny and Biogeography of Juglans (Juglandaceae) Based on matK and ITS Sequence Data. Am. J. Botany 87(6):872- 882. [Although treated as a distinct species in Stanford et al., the data presented and discussed in this paper address higher level taxonomy in the genus (they indicate that Juglans and four sections are monophyletic), and are not relevant to the issue of which rank is appropriate for what is called Juglans californica var. hindsii in The Jepson Manual [Ed. 1].]
Correspondence 4 22 Feb 2006 e-mail from Alan T. Whittemore, The Jepson Manual [Ed. 2] Author, to Margriet Wetherwax see Comment 4
Editorial Comments 4 Correspondence 4 indicates that Alan T. Whittemore, The Jepson Manual [Ed. 2] Author, does not consider mere citation of the same author and epithet to be nearly enough to constitute an indirect reference, stating (with examples) that many authors during the period in question used the same epithet more than once in the same genus, and that each of these would have to be considered new combinations on a single name if such loose standards were adopted, and that he therefore considers the correct author citation to be Juglans hindsii Jepson ex R. E. Smith, Univ. Calif. Agric. Exp. Sta. Bull. 203: 27. 1909. [Therefore, author citation changed to Juglans hindsii Jeps. ex R. E. Sm., from Juglans hindsii (Jeps.) Jeps. ex R. E. Sm. previously in this Index, 23 Feb 2006.]
Correspondence 5 Treatment submitted for The Jepson Manual [Ed. 2] by Alan T. Whittemore see Comment 5
Editorial Comments 5 Correspondence 5 indicates that for The Jepson Manual [Ed. 2], Juglans californica S. Watson var. hindsii Jeps. is to be treated as a synonym of Juglans hindsii Jeps. ex R. E. Sm.
