Correspondence 2 26 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 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 3 Treatment submitted for The Jepson Manual [Ed. 2] by Alan T. Whittemore see Comment 3
Editorial Comments 3 Correspondence 3 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.
