Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 9 Dec 2009 e-mail from Jeff Greenhouse see Comment 1
Editorial Comments 1 Correspondence 1 indicates that, according to TROPICOS, International Plant Names Index, and Flora North America, Cirsium canovirens was published by F. Petrak (Petr. in Authors of Plant Names) in Beihefte zum Botanischen Centralblatt 35(2[2/3]):540--541 (1917), predating the Rydberg publication of that name [also 1917, evidently earlier in the year], and that it was based on Carduus canovirens Rydb. (Memoirs of the New York Botanical Garden 1:450. 1900). [Therefore, author citation corrected to Cirsium canovirens (Rydb.) Petr., from Cirsium canovirens Rydb. previously in this Index, 17 Dec 2010.]
Correspondence 2 Treatment and author notes submitted for The Jepson Manual [Ed. 2] see Comment 2
Editorial Comments 2 Correspondence 2 indicates that for The Jepson Manual [Ed. 2] Cirsium canovirens (Rydb.) Petr. is to be treated in part as a synonym of Cirsium cymosum (Greene) J. T. Howell var. canovirens (Rydb.) D.J. Keil, and in part as a name that in California has been misapplied to plants belonging instead to Cirsium inamoenum (Greene) D. J. Keil var. inamoenum. [Therefore, in addition to Jepson Flora Project-1a, Jepson Flora Project-8 or Jepson Flora Project-8a would also apply.]
