Initial Editorial Analysis 31 Jan 2011
Notes on Authorship of Name both = Authors of Plant Names
Source of Report for California Kartesz & Meacham
Initial Editorial Comments Gnaphalium collinum listed as synonym in Kartesz & Meacham, so evidently treated in different genus in The Jepson Manual [Ed. 1]; not in Gray Card Index; author citation uncertain, both Euchiton gymnocephalus (DC.) Anderb. (Op. Bot., 104: 167.1991) and Euchiton gymnocephalus (DC.) Holub (Folia Geobot Phytotax., 9(3): 271. 1974) in International Plant Names Index-Index Kewensis., Euchiton gymnocephalus (DC.) Anderb. in Kartesz & Meacham.
Editorial Recommendation author citation to be checked [resolved]
Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 17 Oct 2002 e-mail from Kim Kersh see Comment 1
Editorial Comments 1 Correspondence 1 indicates that specimens entered previously into SMASCH as Gnaphalium collinum Labill. have been entered as either Euchiton gymnocephalus (DC.) Holub or Euchiton involucratus (G. Forster) Holub....based on annotations by Guy Nesom, in connection with a treatment he is preparing for Flora North America. [It is not clear why Nesom did not use Euchiton collinus (Labill.) Cass. (Dictionnaire des Sciences Naturelles 56. 216. Sep. 1828) for any of the California specimens.]
Correspondence 2 20 Oct 2005 e-mail from Jeff Greenhouse see Comment 2
Editorial Comments 2 Correspondence 2 indicates that the combinations Euchiton gymnocephalus, Euchiton involucratus, Euchiton japonicus, and Euchiton sphaericus were all published by Josef Holub (Holub in Authors of Plant Names), in Folia Geobotanica et Phytotaxonomica 9(3): 271 (1974), and that these combinations as published in 1991 by Anderberg (Opera Botanica 104:167. 1991) were superfluous. [Therefore, author citation correct as given in this Index.]
