Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 6 Apr 2000 e-mail from Barbara Ertter see Comment 1
Editorial Comments 1 Correspondence 1 indicates specimens previously identified as Geranium solanderi now filed as Geranium potentilloides.
Correspondence 2 6 Sep 2001 e-mail from Barbara Ertter see Comment 2
Editorial Comments 2 Correspondence 2 indicates Carlos Aedo, who is contributing the treatment of Geranium for Flora North America [and may be new contributor of Geranium for Jepson Flora Project], recognizes Geranium solanderi and Geranium potentilloides as separate taxa, and has annotated specimens of both in UC [including, presumably, specimens of both from CA].
Correspondence 3 30 Aug 2005 e-mail from Jeff Greenhouse see Comment 3
Editorial Comments 3 Correspondence 3 indicates that Geranium potentilloides was published by Augustin Pyramus de Candolle (DC. in Authors of Plant Names) in Prodromus 1:639 (1824), wherein he ascribed the name to "L'her! mss." but supplied his own description. [Therefore, author citation expanded to Geranium potentilloides L'Hér. ex DC., from Geranium potentilloides DC. previously in this Index, 1 Sep 2005.]
Correspondence 4 5 Dec 2005 e-mail from Jeff Greenhouse see Comment 4
Editorial Comments 4 Correspondence 4 indicates that, according to Carlos Aedo, The Jepson Manual [Ed. 2] author: Geranium pilosum Sol. (1786) is a nom. nud.; Geranium pilosum Sol. ex Willd. (1801) is illegitimate, being a later homonym of Geranium pilosum Cav. (1788), which applies to a different taxon; and Geranium pilosum Sol. ex Willd. is a synonym of Geranium solanderi instead of Geranium potentilloides.
Correspondence 5 Treatment submitted for The Jepson Manual [Ed. 2] by Carlos Aedo see Comment 5
Editorial Comments 5 Correspondence 5 indicates that for Jepson Flora Project Geranium potentilloides and Geranium solanderi are to be treated as separate species, and that Geranium potentilloides is to be treated as naturalized in CA.
