a 8 Feb 2002 e-mail from Margriet Wetherwax: Geranium columbinum L., Sp. Pl.: 682 (1753) Recognized as occurring in California (native) by Flora North America author - See Aedo, C. 2000 Anales jard. Bot. Madrid 58(1):39-82. 2 records cited (MO, MA) from Ferndale, Humboldt Co., and Winters, Solano Co.
b Hrusa et al., Madrono 49(2)61-98. 2002: DIST: NCo, ScV: Hrusa et al. Current Status: No current information: DOC: Humboldt Co.: ca 7.5 road miles south of Ferndale, along Wildcat Road near Green Pond ranch. May 20, 1987, Pykala and Norris 751 (MO); Solano Co.: 5.6 miles W of Winters. April 16, 1968, Ishizuka 19 (MA): NOTES: Acc. to Aedo (2000) this is a relative of G. carolinianum L., native to the Old World but widely distributed in the northeast US; also in Oregon and Washington.
Initial Editorial Comments Source a indicates that, citing Carlos Aedo (00), Flora North America author, Geranium columbianum occurs as a native in CA; indicated no nearer to California than OR in Kartesz & Meacham. [In lieu of consideration by The Jepson Manual [Ed. 1] author, a Current Status of tentative 1 is appropriate.]; according to Source b, status uncertain (19 Feb 2003).
Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 5 Dec 2005 e-mail from Jeff Greenhouse see Comment 1
Editorial Comments 1 Correspondence 1 indicates that the citation under "Source a" for the report of Geranium columbianum in CA, Aedo, C. 2000 Anales jard. Bot. Madrid 58(1):39-82, indicates that the species is introduced in N.Am from the Old World, but does not address whether or not it is naturalized in CA. [Therefore, Current Status of tentative 2 is appropriate until the issue of naturalization is addressed by Aedo, The Jepson Manual [Ed. 2] author.]
Correspondence 2 Treatment submitted for The Jepson Manual [Ed. 2] by Carlos Aedo see Comment 2
Editorial Comments 2 Correspondence 2 indicates that Geranium columbinum L. is to be treated as naturalized in California in The Jepson Manual [Ed. 2]
