Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 1 Dec 2004 e-mail from Misa Ward see Comment 1
Editorial Comments 1 Correspondence appended verbatim is pertinent to The Jepson Manual [Ed. 2] account: "Need quads for SCM and SCT islands. Equals Haplopappus venetus subsp. furfuraceus, a synonym of I. menziesii var. menziesii in The Jepson Manual. See Leaflets of Botanical Observation and Criticism 1:172 (1906) for original description, and Phytologia 70(2):69-114 (1991) for taxonomic treatment."
Correspondence 2 8 Aug 2007 e-mail from John Strother see Comment 2
Editorial Comments 2 Correspondence 2 indicates that, thanks to encouragement from Scott Simono [of the Jepson Flora Project], the taxonomy and nomenclature of G. L. Nesom (author of Isocoma for The Jepson Manual [Ed. 2]) in Flora North America has been used for specimens of Californian isocomas in JEPS and UC, so that the names Isocoma menziesii (Hooker & Arnott) G. L. Nesom var. decumbens (Greene) G. L. Nesom and Isocoma menziesii (Hooker & Arnott) G. L. Nesom var. diabolica G. L. Nesom (neither used by M. A. Lane in The Jepson Manual [Ed. 1]) now are used.
