Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 $ 8 Feb 2002, from Margriet Wetherwax see Comment 1
Editorial Comments 1 Correspondence 1 indicates that: this name is "in synonymy citation under Opuntia erinacea var. erinacea" in The Jepson Manual [Ed. 1]; that Bruce D. Parfitt, The Jepson Manual [Ed. 1] author, indicated in 1998 that it is based on a "brown-spined form of Opuntia polyacantha polyacantha from New Mexico"; and that the statement "Pl with brown spines have ben called O. polyacantha Haw. var. rufispina (Engelm. & B.J. Bigelow) L. D. Benson" was added to DM [The Jepson Desert Manual]. [However, "...not O. rufispina Engelm. & J. Bigelow" listed in brackets under Opuntia erinacea var. erinacea in The Jepson Manual [Ed. 1], as well as in TJDM, which means it was not treated as a synonym in The Jepson Manual [Ed. 1] and TJDM, but rather as a misapplied name or a name for a taxon not occurring in CA. The quoted statement that was to have been added to TJDM, a statement that would have established the taxon as a minor variant of Opuntia polyacantha that is present in CA, evidently was added nowhere in TJDM. The statement by Bruce D. Parfitt that this taxon is based on a form from New Mexico could mean that the type material was from New Mexico, and that the taxon might or might not occur elsewhere, or that the taxon only occurs in New Mexico. Thus, it seems appropriate to retain Current Status as unresolved at this time.]
Correspondence 2 14 Aug 2002 e-mail from Jeff Greenhouse see Comment 2
Editorial Comments 2 Correspondence 2 indicates that Engelmann was the sole author of the publication in which Opuntia missouriensis var. rufispina, the basionym, was published, but that he ascribed the new name therein to Engelm. & J. M. Bigelow. Thus, in accordance with Art. 46.2, ICBN (St. Louis Code; in part, "authorship of a new name or combination must always be accepted as ascribed, even when it differs from authorship of the publication, when at least one author is common to both."), the correct citation is Opuntia polyacantha var. rufispina (Engelm. & J. M. Bigelow) L. D. Benson, corrected from Opuntia polyacantha Haw. var. rufispina (Engelm. & J. M. Bigelow ex Engelm.) L. D. Benson previously in this Index.
Correspondence 3 5 Dec 2003 e-mail from Jeff Greenhouse see Comment 3
Editorial Comments 3 Correspondence 3 indicates that Bruce Parfitt (The Jepson Manual [Ed. 1] co-author), in the 1 Jun 1998 e-mail to M. Wetherwax referred to in Correspondence 1, stated "This is a brown-spined form of O. polyacantha var. polyacantha in New Mexico, though Benson often applied the name to O. erinacea specimens too. I have studied the polyacantha group in detail and do not recognize rufispina as a taxon."; Parfitt also commented that Opuntia polyacantha var. rufispina was not originally applied to California plants and the reports from California were based on misapplications by Benson.
Correspondence 4 Treatment and author notes submitted for The Jepson Manual [Ed. 2] by Bruce D. Parfitt see Comment 4
Editorial Comments 4 Correspondence 4 indicates that for The Jepson Manual [Ed. 2] Opuntia polyacantha Haw. var. rufispina (Engelm. & J. M. Bigelow) L. D. Benson is to be treated as a name that has been misapplied in California to pls belonging instead to Opuntia polyacantha Haw. var. erinacea (Engelm. & J. M. Bigelow) B. D. Parfitt.
